Playlist Types + AutoDJ Scheduling Options

I would like to suggest a better view of valid combinations of Playlist Types + AutoDJ Scheduling Options. For instance, one can choose "General Rotation" + "Interrupt other songs to play at scheduled time" for a playlist when this playlist currently has no scheduled times. This will have no effect at all and creates confusion. The same applies to the combinations "Once per x Songs" or "Once per x Minutes" or "Once per Hour" + "Interrupt other songs to play at scheduled time".
