Would like more speed options

I use this to track a vehicle. The speed alerts are great and have been reliable thus far. I believe the 10 mph increments are a bit much. The speed limits my teen is in is a 5mph road. I get alerts for 56 daily. We live where there are a lot of hills. Give us 5 mph increments so I can set this at 60, or give us custom levels. Otherwise I am pretty satisfied with the device and app. The text alerts are a nice feature too.
