Your slideshow should be in the Outline tab, so you should be able to drag the track over a blank menu and hold there until the drop option menu comes up. Use the Create Button and Connect to Track option and set the target to Not Set. Then add the button(s) you intend to use and link them to the appropriate track. Finally, enlarge the button made from the Outline tab to cover the entire menu and sent it to the back. That should do the trick, worked for me.
