Cuelist sync and fixture/cuelist exclusivity?

I just did a show that I programmed the media ahead and gave it a dedicated cuelist. Then I programmed movers and conventionals in another stack. I ran into some difficulty keeping up with the programming needs and some values for the media server were tracked into the Light cuelist. I have three questions:

Is there some way to declare that certain fixtures are only accessible to certain cuelists?

Is there any way to sync between stacks that same way two consoles sync? (I go on cue 30, you go on cue thirty, if you don't have a 31, I just go and you remain the same.)

Or is there a better stronger way that you more experienced media programmers can suggest? I've got several years of movers and conventionals, but am squeaky-new to media and would appreciate help and advice.

Thank you,

Mark LaPierre
