360° Pan: be able to change the cam target's height

Hello
I was suprised you can’t change the cam target’s height when doing 360° pan.
It would be nice to track a target as seen from a drone. You set up the center of the 360° pan (= target), then set the circle diameter, the cam height (by default it’s the same height as the target thus it gives a horizontal 360°), and last the start and end points.
