[Suggestion] Stage Background Chooser

[Jedimaster76]

There are some stages that I noticed that have randomized backgrounds (MM9TOR & MM6KNI are the two I can name off the top of my head). I think that a background chooser for these stages should be a thing. The way I see it is that it will be placed in the same area and act very similar as the Music Chooser for MM8TEN, MMKENK, MMKPUN, & MMKBAL. This is just a suggestion though so I understand if this doesn't make it into the game.
