Missing option to use Jog Wheels like this one

I miss out on the option to use Joh Wheels like in the real Machines. I know Mach 3 Machines have em.
Could this be a future implementation?

Something like this?

One can use such things in certain communication / control programs. Chilipeppr has support for the Contour Design ShuttleXpress. See:
