Move Stops between Routes
Move Stops between Routes by activating Multi-Select Mode in Map View or in List View:
in Map View, tap the three dot “more” icon at the top right of the screen and select Stops.
in List View, long-press the circle icon next to any Stop.
Select all of the Stops you would like to move by tapping on them, then tap the action grid icon at the top right of the screen.
You can select all of the Stops with the Select All button at the top of the screen--but if you are looking to move all of your Stops to a new Route, consider duplicating your Route instead.
You can use Copy or Move to get your Stops where you want them -- Copy will create new Stops on that Route and keep them on your original Route too, while Move will remove them from the original Route before adding them to the chosen Route.
After you choose Copy or Move, you can create a new Route with those Stops, or add them to an existing Route.
