Just mute all tracks but the drum. At the bar you want to change tempos or styles press F5. You can make a 200 some bar song, with changes in tempo and style, and then set it to repeat X times. I can't see why this doesn't work.

Just start out with something and go to bar 20 press f5, and make your change. As I said, mute all the other tracks.
