Velocity one yoke caravan ground idle

Well I managed to get the reverse thrust to work on the caravan with the velocity one yoke throttles, pulling back past the detent just goes full reverse, but I cant get it to go in the range between flight idle and reverse, makes it a huge pain to taxi without ground idle. Any thoughts? How is everyone else configuring this?

Have you tried binding the prop control as you would for a piston engine to get flight and ground idle?
