Ich mache das genauso, zu erst wird die Route mit Start und Stop festgelegt und mittels Stops und Vias entsprechend angepasst. Der Unterschied zwischen Inserting oder Adding Stops und Vias ist gut auf der Webseite von DeLorme

What is the Difference Between Inserting and Adding Stops/Vias in a Route?
Many DeLorme programs provide you with the option to add or to insert a stop/via. This document describes the difference between the two options.
Inserting a Stop or Via
When you insert a stop or via, the program calculates the most efficient route between the start and finish points. The picture below shows a route with a start, finish, and 3 stops. In this scenario, the user placed the stops in random order and relied on the program to change the order of the stops based on the quickest way to complete the route.
Adding a Stop or Via
When you add a stop or via, the route is calculated based on the order the stops and vias were placed in the route. The picture below shows a route with a start, finish, and 3 stops. In this scenario, the user placed the stops in a specific order and did not want the program to edit the order of the stops for efficiency.
