Using multiple buttons in a movie clip

Hello,

I’d like to know if it’s possible to have several buttons in a single movieclip that can interact with things outside of that movieclip? An earlier test failed due their instance names not being found, I’d like to think it were possible though.

My reason for asking is that I’d like to control the visibility/position of a large group of buttons simultaneously via AS3 while keeping to a single frame.

Thanks in advance.
