XML slideshow within an xml slide show

Hi Everyone, I’ve been working on a slide show I learned from this site. The one with a sliding thumbnail, which I think is awesome. And I incorporated another slide show within that displaying 1-whatever number of pics. My client wants full control of the site and I can’t seem to get it right since it’s asking for another xml document from the 50 other folders that contain slides. How can I tell it to look inside the folders so that I don’t have to rename each xml document to access the pictures. pretty much I have 50 “listing.xml” files and I don’t want to rename them since that defeats the purpose. PLease help
