Copy/Move a movieclip from _root to inside an MC

Hi again,
If I have a movieclip on the main timeline, is there a way to put this movieclip inside another movieclip on stage (ofcourse during runtime) ?
I know that one of the methods of doing this is using bitmapdata class to capture an image of the movieclip (draw method), then attaching the object it to another movieclip that can be anywhere, but this will make the movieclip lose it’s interactivity behaviour, and vector quality.

Any other ideas?
