Rehearsal marks

[Iosonoilprologo]

Sherry, it sort of helped. I did a start like you indicated and it worked. However to begin with, it gave me kind of a three bars "heads up" which I don't really need. Then it went seven bars after my rehearsal mark # 2 before it clicked back to the 3 bars prior rehearsal mark # 1. Is there a way to fine tune it so it would start at exactly reharsal mark #1 and end at exactly rhearsal mark #2? I have a deadline to master this piece and the silent bars that I don't need are taking time from valuable practice time.
