Is it possible to set up a Presentation that would show a different slide in the same slot based on time around the presentation is playing.



For example: the first time the presentation plays the last slide is 8A. The next time the presentation plays it inserts slide 8B?

There's a free AddIn PlanPoint that may do what you need

Thank you John. That helps for slides that I want to start and stop at a certain time. It doesn't have multiple timers though, so I would have to make a number of copies of a single slide and time each one.
