Making independent sheets for musicians

Hi,
Sorry if this is a silly question but I have only just started using musescore and I really need help with this
Basically my band and I are trying to play a Pirates of the Caribbean medley that I have downloaded off of musescore, however this is only the master copy with all of the instruments on, and the musicians would much prefer to have their own individual copies with only their own instruments on.
Is there an easy way to copy and paste big chunks because i have tried the shift clicking method but that is very difficult as it requires a lot of zooming out to see the entire score, and so I cant accurately click on the end of each bar.
I can't find a guide for this anywhere which seems weird to me as i would have thought that this would be a common issue. Or i guess it might just be impossible
Any help would be greatly appreciated.
Thank you
