Launch a Playlist from a Playlist

Launching a Playlist from a playlist item would be very useful for us for a particular use case.

I'm thinking of replicating an alert functionality like other signage providers have using the schedules to start a playlist, at certain time start another playlist, and upon completion of the interruption go back to a specified playlist.

I could also see this beneficial in a kids room scenario where clean up or other procedural media is on a separate playlist than the main content playlist which might be shared with At Home.
