Eclipse java - Different code templates for different source folders

Question

Is there a way to set up different "generated code templates" (to be clear, not the completion templates that come up when you press ctrl+space, but instead the ones accessed at Window -> Preferences uner Java -> Code Style -> Code Templates) for different source folders in an Eclipse project? If it isn't a built-in feature, is there a plugin that can do this?

Meaning, that when I create a file in one source folder, it will use one code template, and when I create another file in a different folder, it will use a different code template.

I am hoping to use this for contest programming, where I have one project for all my contests, and a source folder for each individual contest. Since different contests have different input formats, I would like different source folders to have their own "new file" templates.

I am using the latest Eclipse 2018-12, if it matters.
