BaseCamp: How to create Off-road route by following a road + manual draw

Hi all, I always create many off-road track for mtb ride with direct route on basecamp... but this process is very slow, takes many time and is very boring every time to draw manual all route....

is there a way to easy create a route with mountain biking profile to "draw a route following a road or path" on the map (I use open mtb map) and "draw a route manual" when there is no path on the map????

This is possible in the create route in bikemap.net... and is very easy to create an off road route.
