Bar set variations / versions

Your idea

Interface for multiple branches (spanning few bars). Instead of copying around A-B1-C-[empty bars]-(A)-B2-(C), allow A-B-C, where B has a selector for the currently active version.

Bonus: Sometimes the variation is only a few notes ("This E♭ could be a C"), it could be shown as a faint ghost?

Problem to be solved

I transcribe recordings with multiple takes, where I'm not quite sure which one is the best. I add empty bars for the other takes, and copy-paste a lot over. System text is used to keep track which part is supposed to link with what, and randomly-generated alphanumerics to link the parts to the recording markers in Reaper.

Experimentation, as well, is slow and messy. It demands discipline to label everything, save-close file-duplicate-label-open copies-keep track which is which.

Prior art

Similar workflow I've seen people use in Ableton Live timeline: disabled clips.

Additional context

This feature could be extended by plugins for better writing of performer-picks cycles popularized by Philip Glass.

No files, tests, or entry points are named. Start by mapping how MuseScore represents bars and edits notation, then examine the desktop interface areas involved in selecting alternate versions. Done would require an agreed design and implementation for multi-bar branches, version selection, and the optional faint variation display.
