On device way types for planned route

No idea if this has been asked before, apologies if so, but I'd love for my planned route to have a slight different line for on-road and off-road surface/way types - like it shows on Strava post rode. Just something which tells me when I'm approaching a road/paved part of my route, or a path/gravel/trail part. Doesn't need to be too complex, just paved and unpaved.
