Improve Garage to Garage missions

I spend most of my time playing Garage to Garage missions in Italy Map but the vehicles are often repeated, even though I have many Mods like the KLJP Pack that add several new vehicle configurations, the game continues to generate repetitive vehicles or sometimes completely unusable offroad vehicles, I have to restart the missions several times to be able to get a "different" random vehicle, so I would like to know if it is possible to somehow modify this vehicle selection system for example to completely exclude offroad vehicles or at least increase the chances of not having so many repetitive vehicles. If anyone knows please help me
