Scores with alternative versions

I have a score with multiple flows and multiple players; singers and instrumentalists. For some flows, the instruments play colla parte, and I would like to exclude the instrumental staffs from the score when they play with the singers, but having them appear when they have other parts to play. Is that possible to do in setup, or do I have to individually hide/show staffs in Engrave?

If these instruments have music that you want to appear in the instrumental parts for those flows, but not in the score, I think the simplest way to handle this requirement is to hide those staves with music on using manual staff visibility changes:
