Resume Where You Left Off (Playlist to Playlist)

would be nice if you can resume to your played playlist where you left off even if you switched to another playlist. 

say i'm playing Playlist 1 and switched to listen to Playlist 2 and then wanna switched back to Playlist 1. i want to resume the song i was listening to in Playlist 1 where i left off and not from the start of the playlist.

thank you.
