I frequently find myself wanting an exit animation for the content of my slide immediately before the transition to the next slide (for example, the text might zoom out of view before the whole slide dissolves). Currently, the only way to do this is to duplicate the slide and set automatic timings on the duplicate, which means that if anyone wants to edit the slide, they must edit both copies. It would be really nice if you could tell Powerpoint to advance the slide after a certain animation plays (maybe a special "advance slide" event in the animation timeline?) or set animations as occurring a certain amount of time before the slide transition.
