Differentiate the color of the planned route between road and trail

I am an Italian firefighter using Locus Map 4 Gold
For search and rescue operations, I’ve set up a profile that bypasses mountain barriers and finds the fastest route to the target. However, I need an intuitive way to see exactly how far I can drive my off-road vehicle.

Is it possible to implement an automatic visual distinction (e.g. using color) or mark the point where the road turns into a trail?
Does such a tool already exist in LM4? Could it be developed in the future?
