How do I define and assign Subnet and IP addresses to Containers using Docker compose

I think what I am trying to do is straight forward, but reading through the docker compose documentation section on Networking https://docs.docker.com/compose/networking/ I find no useful information :(

I want to create 2 subnets (this could be more in the future - but for now, let's have it at two) and be able to manually assign IP addresses from each subnet to the container I specify in docker-compose.

How can this be done?

Use this compose file, you can add as many n/w's you want:-

version: '2'
services:
  mysql:
    container_name: mysql
    image: mysql:latest
    ports:
     - "3306:3306"
    networks:
      mgmnt:
        ipv4_address: "192.168.80.5"
  tomcat:
    container_name: tomcat
    image: tomcat:latest
    ports:
     - "8080:8080"
     - "8009:8009"
    networks:
      mgmnt:
        ipv4_address: "192.168.80.6"
      local:
        ipv4_address: "10.10.0.10"  
    depends_on:
     - mysql

networks:
  mgmnt:
    driver: bridge
    ipam:
     config:
       - subnet: 192.168.0.0/16
         gateway: 192.168.0.1
  local:
    driver: bridge
    ipam:
     config:
       - subnet: 10.10.0.0/16
         gateway: 10.10.0.1
