Play around with the Fakesheet bars/line found in the Leadsheet Opt screen. It defaults to 4 bars/line but you can enter anything there. Some examples:

8 - 8 bars/line
8,4 - 8 bars on first line and 4 on remaining lines
4,4,6,4 - 4 bars on first two lines, 6 bars on next line and 4 bars on remaining lines

I've done stuff like 4,4,4,6,4,4,8,4 to get my score on one page

Good luck,
