Nested buttons

if i put a button mc inside another button mc, is there anyway to have onRollOver actions on both of them activate at the same time?

for example one mc onRollOver would change color, then nest that inside another mc that would onRollOver change alpha. so the end result would both change color and alpha at the same time.

there’s a more complicated reason for this but i’m simplifying it to try to make more sense.

thank you.
