Movie Clip Duplication Problem

Not sure how to do this, but I have a rather elaborate button that I have converted into a movie clip and I want to duplicate that button into several others that look just like it, but have different images on them. The problem is that when I duplicate the clip in the library, and then edit the new clip, I don’t want those changes to reflect in the original clip. I just want to be able to duplicate the original button, and then edit the copy to make another button independant of the original. I would think that this would have a simple solution, however, it seems to be eluding me at the moment. My appreciation for any help that can be given.
