Add AWS CodePipeline action to existing pipeline via CloudFormation

I've made a CodePipeline pipline CloudFormation template and deployed it as a stack. I'd like to add an action to this existing pipeline via another CloudFormation stack.

From the documentation I can only see pipeline resources which would allow me to create a whole new stack, not edit an existing one by providing an ARN or something similar. There are also no granular resources that provide support for CodePipeline functionality such as actions. See URL below:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-codepipeline-pipeline.html

Does anyone know how I can achieve this? By the looks of it I'd say I have to update the template for the pipeline, adding the new action. Assuming this is the only way, how could achieve this from another CloudFormation stack?

So a template would be configured to add a new action in the pipeline template, and then trigger an update of the pipeline stack. I'm guessing I'd have to use a CloudFormation macro and keep the pipeline template stored in s3. I'd then take the template out of s3, add the action, save the change and then what? I've also considered how I might use nested stacks or the Import macro.

Thanks for any help!

@Marcin inspired me to this solutions. Thanks :)

Essentially I did this:

First I created a "Change" pipeline that took the stack template modified during the build stage, that I originally wanted to deploy across multiple stacks in a deploy action, and wrote it out to the path within an s3 bucket.

Second I created a "Deploy" pipeline that used the s3 path pointing to the output of the "Change" pipeline. This pipeline contains a deploy action that uses a SourceArtifact of the outputted template. This is essentially the deploy action I wanted in the "Change" pipeline.

I have now created a CFN template for the "Deploy" pipeline, allowing me to create any number of "Deploy" pipelines pointing to different stacks. When the "Change" pipeline is triggered it's output triggers all the "Deploy" pipelines. My approval and testing process goes into the "Change" pipeline to avoid spam and I can roll back no problem.
