@Anonymouse ...ah got it. By default, each new entered Waypoint becomes a Shaping Point - except the first and last point; they are always Via Points.
Would be helpful in your case, in the moment, you are entering a point, a question asks: as Via- or as Shaping Point.
I'm working a bit different: I know where to start, setting the first Waypoint. Then I know roughly my target/destination an enter the second Waypoint (which is the last Waypoint). Immediatelly I see the distance and can decide it's ok, or to far away for a day trip.
If distance is roughly ok, I search for lovely route and force the rout line to a dedicated street. This gives me Shaping Points (in the rigth Order).
Then - depending on distance and time - I enter additional Way Points for Restaurant, or Fuel stop. Because that are only a couple of, it's not a big work to change them to Via Points, because I'm changing the colour, so it's not an extra effort to change in this moment also the type.
