Add a feature existing template

Hi, i need to add a feature to an already available source fla template. This flash template read all data from a [login to view URL] the actual template change a slideshow (as background) each menu item. What i need is to add a feature that change the slideshow also for the submenu item. Of course all images are called from the xml file. I have the source code (fla) of the version before. That one just with slide show on each item of the menu. Thanx Renato
