- Open the route (Route_01_Example)
- Open the option routes via the dropdown menu on the left
- There, select the route that you want to merge into the opened route.
- The selected route (Route_02_Example) is added as a yellow line to the previously opened route (Route_01_Example).
- Now click on the '+' sign to merge the route (Route_02_Example) with (Route_01_Example)
- Choose where you want to merge the route with the previously opened route (Route_01_Example).
- In this case at the back!
- Click merge.
- Check whether all route points are correctly positioned on the route line!
