Wow, thank you for the quick response, it's good to know that there's no elegant answer and that I need to resort to two documents, so I'll stop wasting time and go ahead and do that to get past the current challenge. Thanks again.
Sorry in advance, but I'm not an advanced user, and I am working on entering a handwritten song sheet for a male choir, for a piece in which a bass clef shows up for the last few bars (11) of a piece. I want to enter that last part of the song using two staves, but just show (print) the one (treble) staff for the first pages of the score. There must be a way of making a break in the song at the end of the single-staff part, and starting with a multiple-staff system from that point on, but I'm not seeing how to do that. I know I could enter an empty bass staff with invisible rests up to that point, but then it seems to print - that is I can make the contents of the staff up to that point invisible, but the staff lines still print. Help please!
