This feature had been there all along (by means of an adapter). But warthog's heavy stick didn't go well with the pincer-type mechanism in the base. The stick felt limpy and leaned forward under its own weight. I had to add some more springs to keep it centered, but it resulted in a way too jumpy transition across the axis center. So I decided to leave it in default configuration with the default stick.
Hopefully this new cam mechanism will let us use such heavy sticks comfortably without the above mentioned problem.
