Flash Pro 8 [AS 2.0]

I have my main fla into which I load (loadMovie) an external swf into an emptyMovieClip.

On the external swf I have an image of a door set up as a button. On clicking the door I would like the external swf (in which the door button is a part of) to unload from the main fla. Is it possible for a button within an externally loaded swf to unload itself from the main fla into which it is loaded?

Thank you.
