After setting up a navigation route – allow options to change the route and/or insert waypoints of additional planned stops along the way.
This is particularly useful when you know a faster route for a portion of the trip that auto-routing avoided since it’s not a freeway.
Common in many navigation systems, but does add some complexity to the usability.
Implemented in version 2021.40.5, but called “Add Stop”. From the release notes “Add a new stop to your route by tapping the ‘+’ icon on the navigation search button and searching for a destination, or selecting a pin on the map.”
