Using multiple configuration templates

I'm almost certain this used to be a feature, and maybe it's just that I can't find it anymore, but here's my request:

I want to use configuration templates to easily set up Python run configurations across multiple tasks and files in a project. This is because the project's codebase relies on certain working directory and environment variable settings

Under “Edit configuration templates”, I can edit the Python template, and obviously I also have Python docs and Python tests and Python Debug server.

I know that at some point, it was possible to define multiple “Python” configuration templates. In my case, I need one for “module” (all pointed to the same __main__", and one for scripts.

Currently, I just have to make pseudo-templates and copy them.
