How to set up Prop Pitch on HOTAS

[pandacat]

Hi, I am looking for a right way to setup my PP control on my x52pro Hotas. Currently I have it mapped to the slider on throttle. It works fine, but I found the range between 0% to 100% too wide. I barely get to use anything below 50%. Since I am only using half of the slider range (50-100), one tiny movement alters PP setting big time making fine tuning PP very difficult. I am wondering if there is a way to make the slider only go from 50 to 100 and also make it less sensitive to minute movements.
