[Playlists] Playlists within playlists

I would like to be able to have a playlist automatically include the songs on another playlist and when a song is added it adds it to all the playlists. e.g.:
Playlist A = Song 1, Song 2, Song 3
Playlist B = Playlist A, Song 4, Song 5 = Song 1, Song 2, Song 3, Song 4, Song 5
Playlist C = Playlist B, Song 6, Song 7 = Playlist A, Song 4, Song 5, Song 6, Song 7 = Song 1, Song 2, Song 3, Song 4, Song 5, Song 6, Song 7

 

And if I were to add Song 8 to Playlist A:
Playlist A = Song 1, Song 2, Song 3, Song 8
Playlist B = Playlist A, Song 4, Song 5 = Song 1, Song 2, Song 3, Song 8, Song 4, Song 5
Playlist C = Playlist B, Song 6, Song 7 = Playlist A, Song 4, Song 5, Song 6, Song 7 = Song 1, Song 2, Song 3, Song 8, Song 4, Song 5, Song 6, Song 7
