Swap symbol on multiple keyframes?


Is there an easy way to swap symbols on multiple keyframes? Basically say I have mc_A moving up and down with keyframes, now I want to swap it to mc_B, how do I swap out mc_A with mc_B on all the keyframes?

Funny thing is if it is a graphic, all I have to do is swap the first and it will automatically swap the rest. Is there a shortcut for swapping movie clips? Thanks! :sc:
