Picky "Hide Empty Staves" rules
I'm arranging for a show choir and am trying to build a "Vocal & Piano" score. There are 4 instruments in this part: two 1-staff instruments for Solo 1 and Solo 2, a 2-staff instrument for SATB (I just renamed a piano instrument), and a 2-staff piano.
For large portions of the piece, one or both of the Solo staves are empty. For that reason, I tried using "Hide Empty Staves within Systems" to hide those staves when appropriate. However, I'm now dealing with an unintended consequence. In sections where I only use one staff of the 2-staff instruments (ie only left hand of the piano), the unused staff disappears. I'd like to maintain the grand staff for these instruments whenever at least one is used, hiding or showing them as a unit.
So my question is:
Is there a way to hide empty staves on an Instrument-by-Instrument basis instead of Staff-by-Staff?
