Duplicate Movie Clip Target

Is there anyway I can tell duplicateMovieClip a target?

For example I have a set of elements that dont fit on the stage(width). I want to create a scrolling device to scroll through the elements and users can drag them to a stage which will duplicate the movie clip.

When I created the scrolling device it scrolled the elements AND the duplicated clip.

Is there any way I can tell .duplicateMovieClip a target of another movie to dup. the clip?
