Multiple Motion Zones Battery Doorbell

My front of house doorbell has to be at an angle since my steps zig zag in front. I’m having a hard time with decent motion detection since I need to limit areas of the image so cars on the street and my neighbors don’t cause it to go off. I really need like 3 custom zones but they need to be similar to the current zone with 6-8 corners so I can perfect it. I had it set to people and the whole screen but the ups and amazon drivers are sneaking past 60% of the time by not ring the doorbell. All motion detection is helping but I am getting 50-60% false alerts by trucks going down the street or kids walking on sidewalk.
