Introductory audio on slides
Hello! I have a menu slide that I'd like to include some introductory audio on (ex: "Click on the boxes below to learn more about each topic") however, the boxes they will click bring them to different slides for more information, and then back to the menu so they hear the introduction every time they return to the menu. Is there a way to have the audio trigger only once, the first time they arrive at the menu slide? Currently I have the audio triggering as soon as the timeline starts, perhaps there is a different triggering method I should be using?
Thanks for your help!
