If you want to have a control on multiple pages (I always do), you've got two options: 1) make a control copy (actions->copy) or 2) make a supercontrol.
If you can deal with the constraints of a copy--same size, exactly, same label size, same behavior--then use that. It's lighter weight.
Otherwise, use supercontrols. If the supercontrol-chain has only one control per level (A->B->C->D etc.) then subs spin supers and supers spin subs, all the way up and down the chain.
But like with anything, save your layout (config -> actions -> save layout) and TRY IT OUT! You can't make an omelet without breaking a few eggs (and sometimes having the landlord throw you out for being completely irresponsible).
