I have a song where I want to harmonize my voice in the 20th Bar. I only want the harmony though for beats 3 and 4. I've tried various combinations of settings but I can't seem to exclude the first two beats. Is it possible to do what I'm trying to do? If so, how do I go about doing it?

I'm running BB Version 2008.5 (264) on windows XP w/ sp 3.

Thanks much.
