With the Sub-Playlist feature, you can add playlists within your main Classic playlist.
In that way, each screen will display, for example, the main playlist, which probably has media for all screens, but each screen can have its own Sub-Playlist.
For example:
Screen 1 will play the Main Playlist and the Sub-Playlist, which will only have Media for Screen 1.
Screen 2 will play the Main Playlist and the Sub-Playlist, which will only have Media for Screen 2.
Screen 3 will play the Main Playlist and the Sub-Playlist, which will only have Media for Screen 3.
