Deleting commits?

Is there a way to delete commits?

Studio seems to occasionally and unpredictably discard all changes made to a sub-symbol, so I’ve started explicitly “saving” (committing) in order to avoid repeatedly redoing a bunch of stuff. As a result, my commit history has been growing faster than normal, and I need a way to clear out old commits.

Anyone know how to do it?

Anyone know how to delete commits so that projects don’t eat up too much storage?
