Thermostat Behaves Very Differently With Different Outside Temp???

Bought 2 new 2018 Hondas recently (CRV and Civic). On both, the climate control system acts as if it is driven more by difference between outside and inside temp than by the actual inside temp as I would expect. To maintain consistent inside temperature on the same trip, we constantly have to turn thermostat down when driving through an area that is cooler outside, and up when driving through an area where it is warmer outside. Is there any way to make it just keep a constant inside temp without constant fiddling? I don't see anything in the manual about this.
