The ability to add a custom compose file for the Portainer stack in addition to the compose files from the Git repository

Is your feature request related to a problem? Please describe

The git repository is convenient for committing the basic settings for creating a Portainer stack. However, as a rule, the final stacks have slight differences in different cases.

Describe the solution you'd like

It would be convenient to add a separate compose file (or text for temp compose file) to the Portainer stack in addition to the compose files from the repository. By merging, they will create the desired configuration. When you change the basic settings in the git repository, the stack will also be updated with an additional compose file.

Describe alternatives you've considered

Docker compose has the functionality of merging multiple compose files into a single configuration

docker compose config -f file1 -f file2 -f file3
