The feature works fine. Would it be possible to choose if the new waypoint either will be added to the database as an independend waypoint (as it is now) or to add it to the current cache, if using this feature from there?

So it would be possible to add a "visual" waypoint as next stage or final in mulit caches.

Definitely a good idea

Das wäre auch als Owner interessant Man könnte sich dann eine Owner Maintenance-Vorlage speichern, wenn man eine Reihe abfährt.
