Hi there, I was wondering if anyone knew how to fit more than two grand staffs on one page in the Crescendo notation software? It really bothers me that I can't find a way to add a full new grand staff on this one page even though there is clearly enough space for it. In other words, I would like to have 3 full grand staffs on one page, but I have no idea how (since new staffs just go to the next page). I'm using the voice and piano format on the free version of Crescendo. If anyone could help that would be great!
