How to manually hide/show empty staves?

I'm notating a choral piece and for the most part, hiding empty staves is what I want. I don't need three empty staves during the piano intro/interlude, and more importantly I don't need to split my vocal line into three staves for most of the piece, save for a small section in the middle. But I would like to lead into that section with empty staves until each part enters, rather than only showing one at a time. Is there a way to keep some empty staves visible while hiding all the others? I've been trawling through the musescore forums but so far I haven't found a solid fix. Thanks!
