Print bed 0,0,0 offset from machine 0,0,0

I have a Wilson II and it uses a rack and pinion system to deploy the z-probe switch. Because of this system the machine 0,0 deploys the probe, so the bed 0,0 needs to be offset by about 10 to 13 mm in order for the probe not to deploy when at the bed 0,0 position. Is there a way to configure the firmware so the the bed 0,0 is different from the machine 0,0?
