Enhance Staff Copying: Reassign Voices and Remove Rests

When copying staff contents from one voice to another, it would be beneficial to have an option to reassign voices and remove rests. This is useful when working with complex scores that involve multiple instruments or parts.

For instance, in a SATB + Organ template for traditional hymns, I often separate the organ part into individual choral lines (soprano, alto, tenor, bass). When copying over an organ voice to one of these choral sections, it can cause two voices to merge with different notes and rhythms. Currently, this requires manual editing to delete rests, and one has to re-enter the notes for the first voice.

A feature that allows for automatic voice reassignment (e.g., "voice 2" becoming "voice 1") when copying staff contents would streamline this process. This functionality would save time and reduce errors in score preparation.

To implement this, add a simple button or option for the copy operation to toggle / configure voice assignment, effectively allowing users to:
* Remove rests from copied notes
* Reassign secondary voices (e.g., "voice 2") to primary voices (e.g., "voice 1")

An option would be to have this as a general button to click on to re-assign voices (i.e., perhaps near the voice buttons). This enhancement would improve workflow efficiency and accuracy when working with complex scores in MuseScore.

Update:
I just found out through experimentation that one can paste a note onto a rest and that re-assigns the voice 2 to voice 1. However, it does not carry over the note rhythms.
