Can I animate a presentation using BOTH timed and "on click" advances? Specifically, I would like to have a group of slides, say slides 1-6 automatically (timed) advance and keep repeating (1-6, 1-6, 1-6, 1-6, etc.) AND THEN, upon a click, move on to the remaining slides, say slides 7-15 which advance by clicks until the last slide is displayed.
