Enable the ability to 'fork' a design in Make

It would be really useful to be able to create a branch or a fork in a Make file that can be merged back into the original. Similar to how engineering branches their files. This would allow someone to iterate on an idea without disrupting a prototype that is being used for feedback/testing/presentation.

My current workaround is to duplicate the file but the problem is that creates multiple links. I want one link to share with stakeholders/testers that doesn’t change.

Thanks for your consideration!
