My playlists are set up with the artist and all albums under them. and then I have extra playlist called (favorites) with the ()'s so its at the top of the playlist when selecting them from the player menu, and inside favorites I just throw in all my favorite songs and I set it to auto shuffle so I never hear it in the same order. I think you could do what you want my taking your current playlists and just throw ()'s around them and then add the artist/album under them.
