docker-compose.yml - make network name configurable via environment variable

I have a docker compose file with env variables for stage specific configurations. As long as env variables are used in values in docker-compose.yml everything is fine, but the problem is with the network name, since it's specified in the tag.

networks:
  mynetwork.${STAGE_NAME}:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: ${STAGE_NETWORK_PREFIX}.0/24

Any chance to get the network name mynetwork.${STAGE_NAME} configurable from outside?

It is possible via network name:

networks:
  mynetwork:
    name: ${STAGE_NAME}

where mynetwork - name "inside" stack

${STAGE_NAME} -name for other stacks/services/containers
