I recently plotted a route using the OS mapping app but having finished it I decided it would be better if it was walked in the opposite direction to the one had plotted it. Both Garmin and ViewRanger allow me to reverse a route I have plotted so I can follow it in either direction but I do not seem to be able to do the same function within the OS app. Does anyone know how other than exporting it to BaseCamp of ViewRanger, reversing it and reimporting it?
