Multiple branches for a single project

Hello, As a project creator, it would be nice to be able to have several branches for the same project.

Let me explain: I have a nameplate addon for msfs 2024 and it works fine on Su2 but the addon is broken on the SU3 beta.
I have a corrected version for Su3 but if I only use this one then it won't work for Su3.

So for the moment I've only got two solutions: either I redo a new Upload or I integrate the 2 versions in my compressed file.

It may already be possible, but I can't see where. Thanks
