Simple way to set stick/wheel values?

is it possible or would you be willing to add the ability to simply set values for joysticks and the tilt wheel? I really want to be able to have very slow, smooth controlled motions over a long period of time, such as ascend SLOWLY while also very SLOWLY turning the gimbal down over like 20 minutes. When I try this with waypoints it ends up with a lot of jerky correcting actions to try and maintain it’s heading. Trying to keep my fingers steady for this length of time is just not possible.

The values will depend on/change with the ‘Gain’, ‘Sensitivity’ & ‘Expo’ settings of the sticks, and the ‘Gimbal Pitch Speed’ & ‘Gimbal Pitch Smoothness’ settings.
