Keynote Auto advance to next slide after movie

I am using Keynote to present a series of short films. I want Keynote to automatically play the movie, advance to the next slide and play the next movie and the repeat this same procedure. All the movies are different lengths and some are more than 99 seconds(the max delay on the builds/in and out settings.

Play movie, advance to next slide, play movie, advance to next slide, play movie, etc. All automatically!
