Navigation route preferences

Been using the app for over a year and I have a suggestion.

I use Kuviger for planning road rides, dirt rides, and occasionally for routes with my camper and trailer.

Dirt Routes, while I can set a preference to avoid dirt roads, it would be nice if I could design routes that prefer dirt roads for riding my dual-sport bike.

Camper/Trailer, I know there are apps out there designed for truckers, it would be nice to be able to design a route that avoids the curvy stuff that is difficult with a trailer.

The app is good a designing routes for curvy paved roads, I would like additional options for dirt and trailering
