Yes, highlighting Trails is a combination of some reserved polyline-definitions in the typ-file and an selected Activity on the GPS.

Actually this is how Topo Germany 2012 Pro works. Topo France v3 Pro has all trails highlighted permanently and doesn't depend on a chosen activity. Even in Mapsource the marked trails of Topo France can be seen.
