Is there a way to configure the 'Stack Name' of nested stacks in AWS cloudformation ?

I am trying to create a nested stack using AWS CloudFormation. I need to specify the 'Stack Name' of the nested stack. I tried using the 'Tags' property with Key: 'Stack Name'. But that didn't help. Is there any way to provide the Stack Name as an input while creating nested stack?

As commented below, the answer is no for now.

Original:Yes, it's the resource name that gets taken as the stack name. Below you'd get a stack called myStackName

YAML

AWSTemplateFormatVersion: "2010-09-09"
Resources: 
  myStackName: 
Type: "AWS::CloudFormation::Stack"
Properties: 
  TemplateURL: "https://s3.amazonaws.com/cloudformation-templates-us-east-1/EC2ChooseAMI.template"
  Parameters: 
    InstanceType: "t1.micro"
    KeyName: "mykey"

JSON

{
"AWSTemplateFormatVersion" : "2010-09-09",
   "Resources" : {
  "myStackName" : {
     "Type" : "AWS::CloudFormation::Stack",
     "Properties" : {
        "TemplateURL" : "https://s3.amazonaws.com/cloudformation-templates-us-east-1/EC2ChooseAMI.template",
        "Parameters" : {
           "InstanceType" : "t1.micro",
           "KeyName" : "mykey"
        }
     }
  }
}
}

In a given template, you have access to the pseudo-parameters stackId and stackName. Those can be marked for export, then referenced in another stack. Joined, they give you the child stack's name.

I found the following video quite useful despite its age: https://youtu.be/6R44BADNJA8

This sample template may also be helpful in understanding how these work: https://s3.amazonaws.com/cloudformation-examples/user-guide/cross-stack/SampleNetworkCrossStack.template

{ "AWSTemplateFormatVersion" : "2010-09-09", "Description" : "AWS CloudFormation Sample Template VPC_with_PublicIPs_And_DNS: Sample template that creates a VPC with DNS and public IPs enabled. Note that you are billed for the AWS resources that you use when you create a stack from this template.", "Resources" : { "VPC" : { "Type" : "AWS::EC2::VPC", "Properties" : { "EnableDnsSupport" : "true", "EnableDnsHostnames" : "true", "CidrBlock" : "10.0.0.0/16" } }, "PublicSubnet" : { "Type" : "AWS::EC2::Subnet", "Properties" : { "VpcId" : { "Ref" : "VPC" }, "CidrBlock" : "10.0.0.0/24" } }, "InternetGateway" : { "Type" : "AWS::EC2::InternetGateway" }, "VPCGatewayAttachment" : { "Type" : "AWS::EC2::VPCGatewayAttachment", "Properties" : { "VpcId" : { "Ref" : "VPC" }, "InternetGatewayId" : { "Ref" : "InternetGateway" } } }, "PublicRouteTable" : { "Type" : "AWS::EC2::RouteTable", "Properties" : { "VpcId" : { "Ref" : "VPC" } } }, "PublicRoute" : { "Type" : "AWS::EC2::Route", "DependsOn" : "VPCGatewayAttachment", "Properties" : { "RouteTableId" : { "Ref" : "PublicRouteTable" }, "DestinationCidrBlock" : "0.0.0.0/0", "GatewayId" : { "Ref" : "InternetGateway" } } }, "PublicSubnetRouteTableAssociation" : { "Type" : "AWS::EC2::SubnetRouteTableAssociation", "Properties" : { "SubnetId" : { "Ref" : "PublicSubnet" }, "RouteTableId" : { "Ref" : "PublicRouteTable" } } }, "PublicSubnetNetworkAclAssociation" : { "Type" : "AWS::EC2::SubnetNetworkAclAssociation", "Properties" : { "SubnetId" : { "Ref" : "PublicSubnet" }, "NetworkAclId" : { "Fn::GetAtt" : ["VPC", "DefaultNetworkAcl"] } } }, "WebServerSecurityGroup" : { "Type" : "AWS::EC2::SecurityGroup", "Properties" : { "GroupDescription" : "Enable HTTP ingress", "VpcId" : { "Ref" : "VPC" }, "SecurityGroupIngress" : [ { "IpProtocol" : "tcp", "FromPort" : "80", "ToPort" : "80", "CidrIp" : "0.0.0.0/0" } ] } } }, "Outputs" : { "VPCId" : { "Description" : "VPC ID", "Value" : { "Ref" : "VPC" }, "Export" : { "Name" : {"Fn::Sub": "${AWS::StackName}-VPCID" }} }, "PublicSubnet" : { "Description" : "The subnet ID to use for public web servers", "Value" : { "Ref" : "PublicSubnet" }, "Export" : { "Name" : {"Fn::Sub": "${AWS::StackName}-SubnetID" }} }, "WebServerSecurityGroup" : { "Description" : "The security group ID to use for public web servers", "Value" : { "Fn::GetAtt" : ["WebServerSecurityGroup", "GroupId"] }, "Export" : { "Name" : {"Fn::Sub": "${AWS::StackName}-SecurityGroupID" }} } } }
