hitTest - check which moveclip is hit?

Hello

I can't seem to find out how to check which movieclip is being hit in a hitTest.

What I want to do, is to have some dynamically created movieclips that needs to adjust position (X and Y) according to, if it's dropped on top of another movieclip.

So if I drag mc2 and drop onto mc1, I want mc2 to move X and Y, so they're not on top of eachother.

hitTest is easy if you just check mc1 hitting mc2 but if I have a larger number of movieclips, then I dont know what to do.
I've really searched different forums and google.

Any help is appreciated
Thanks
