XDJ-RX2 JogWheel (Custom) adjustment

Is there any way of adjusting the (mechanical) Jog sensitivity of the XDJ-RX2?

I dont mean the vinyl speed adjust, i really mean the mechanical feedback (which can be adjusted by the Jog Adjust Knob on the NXS Player). I know that you can also adjust the sense on the CDJ 850s, by opening them and adjusting the spring on the inner side.

So: is there ANY way to get the RX2 Jogs a bit heavier (i know, i´ll loose my warranty by opening the player & i´m fine with it).
