Excellent site. Is there a way to add waypoints from a touchscreen (e.g., ipad)? I put in my start and finish points and get a route, but then I'd like to be able to adjust the route slightly, but can't seem to find a way to do so via touchscreen. The app interprets touches as changes to start or finish. And I seem unable to touch the route, hold and then move as I can with a mouse on a laptop screen. Many thanks.
