Have you tried the “Align World” function?

Perhaps it does what you are asking for!

Can you try the latest master? The problem you described should be solved.

Why? I forgot to add that I need to copy-paste UVs within the same object, just different UV layers. Shouldn’t be that difficult to implement I think.
