Make Alias but Copy Folder
I am not sure of the subtlety of copying the folder vs. simply making an alias.
There can be huge benefit to using aliases for recurring parts in a song. Change the original, the alias follows along. It is also quite easy to use the same part, but transposed, using an alias. Logic for the win.
Aliases do have some differences from their “parent” region: you can give each alias its own name, and edit region parameters for each alias independently.
