Motion Zones/Sensitivity for Pathlights

I have a number of pathlights deployed along my driveway. Among other things, their purpose is to inform the house when a vehicle is in the driveway. Though the sensitivity is set to the lowest value, we get a lot of false indications, especially at night. It would be great if I could configure the pathlights to only report if it detected a vehicle in the actual driveway. Thank you, Ken Traynham
