Duplicate Movie to new target path?

Is there some way I can take a movie clip within a movie clip, and create a duplicate version on level0?

to clarify, Movie clip B is in Movie clip A. Make a version of Movieclip B on level0.

I do not want to use attachmovie linkage type of code in this instance. It will not work with what I have to do.

…or is there a way to move Movie Clip B to root?
