Audio From Spotify, Apple Music, or Chrome Window

Would like to be able to set the audio source for a specific section or slide(s) to come from a different application window like Spotify of Chrome. Then when that section or slide ended the audio would stop like a stop audio cue does currently.

This would be extremely helpful as few people buy physical music/audio media anymore and rely on subscriptions to music services like Spotify, Apple Music and more. Thank you!
