Implement Best of 3 and/or Swiss Rounds for Room Tours

[dtsong]

If possible, could there be a feature that can implement "best of three" style battling for room tours? This would be great for the VGC players on Pokemon Showdown to practice playing best of three in a more fluid fashion than having to go around the room looking for people to battle and then having to go through the trouble of making custom battles every time.

Another suggestion would be to add Swiss Rounds to the Room Tours to emulate VGC premier challenges and regionals, that would also be quite amazing if it can be implemented.
