Request to do auto tune in loiter? mode

I’m not sure whether it is too complicate to do that, just I have to chase my drone during the auto tune process, and some time I have to break auto tune process too many times.

If the drone can fly back automatically, after each turns, like loiter mode does, it would be much convenient and we don’t need a large space to do it. And user can often use the “auto tune” mode, when they changed something on the drone.

This is done in 3.5.
