Divisi in separate staves

[Vaughan McAlley]

Greetings,

I’m working on a string orchestra piece which has two cello parts,
both independent enough to warrant separate staves, except for 24 bars
in the middle where they are in unison. It would be nice in the score
to mark it "unis." and leave out the second cello for the duration of
the unison, much like RemoveEmptyStaffContext does with lines
containing rests. It looks like it might be able to be done by using
quotes and telling RemoveEmptyStaffContext that quoted music is
"uninteresting".

Is this possible, or is there a better way to approach it?

Cheers,
Vaughan
