So, this might have been posted elsewhere that I failed to catch, but does anyone know if there is a way to play the Co-op encore stages in single player? Looks like they're not even in Quick Play let alone Career. In my opinion this was a pretty stupid move, I'm dying to play Monsters, but unfortunately I don't know of a way to do so without hooking up another guitar and playing Co-op by myself. Any help is appreciated.
