I'm not a BB expert, but I think you can 'unfold' a song (make it linear) and get a little more control.
That way you could silence the measures until you want them to start.
You may also be able to use F5 to mute/unmute tracks as needed.
I'm sure someone will be along with a better solution, but that's the first things I'd try.

/edit
I may have misunderstood issue, see Trevor's post above
