Allow playing a voice by itself

Thought I'd use MuseScore to teach myself how to sing the parts of a song. The notes are in as separate voices so the notes have different colors.

Turns out though, there is no way of playing back only one voice by itself. Seems it can be "worked around" by separating the voices out as different instruments, but come on... They are the same instrument, so I shouldn't have to do that.

Would be awesome if someone could make this possible.

(Music newbie, so hope I'm making sense here :)
