Route "Combination"

A feature that lets you combine multiple routes from a map to make one route that represents one journey. Example: a skin up route, traverse route, and downhill route are all separate routes on one map, the feature would allow you to combine them into one route in order to show complete mileage and elevation that would be expected if you were to do all those routes as one trip. Would be nice for maps that have lots different routes and hiking maps. This feature would differentiate backtrack from other mapping services.
