hiding empty staves until they are needed

[Sarah k Alawami]

Hello. In lily pond i am creating my final assignment for the semester. Yee! 
lol! except not. 

I don't want to write rests and i plan on maybe writing out the repeats. I 
don't now yet. I want to though hide empty staves until they are needed, then 
hide the staves again. I saw this in a choir score i was reading for one of our 
concerts and wondered if that is possible that way i don't have to write out 
rests. Also how will this effect the parts i will eventually create for each 
player to turn in to the prof.

I have until may 10 probably to complete this assignment and i want to work on 
a bit at a time so i don't get a headache lol!

i'm still using lily pond v 2.16

Thanks. And i'm not looking forward to starting this project. I already have a 
templet i found on the lily pond manual which is close enough. I can probably 
remove the staves i'm not going to use so as not to waist paper or what ever 
the prof will do with it lol!

take care all and thanks for your patience.
