Is there a way to determine how long each slide should be shown for for a certain song? I have a few songs that I want to play and I want the song to play for a certain section of slides then start a new song for a new section. Say my song is 4:03 min and I have 80 slides, I would like to set the slide duration of those 80 slides to last for that song. I would really appreciate any help! Thanks!
