Simple question: How do you rotate through 360 degrees more than once?

Rotating once is easy - keyframe 0 and keyframe 360

Rotating on loop is easy - as above, then "loop"

But rotating a fixed number of times ... How do you get past the keyframe 360? I can't figure out a way to force the animation window to jump the 360 back to 0 again - it doesn't allow that,even though (for rotations only) that should be fine.

Simply increasing the number (360->720, then to 1080, then ... etc) etc kills accuracy and is horrible to maintain. Is that the only option we have?
