I would like to mark points of interest (POI) ahead of time (maybe via Google Saved locations?) and have Waze alert me when I'm near it, without having to plan a complete route to go via those POIs. Whenever Waze realises that I'm within a defined range of that POI it could alert me and offer to guide me there as a waypoint. I don't always plan routes in advance, and even when I do I often wander off-course to investigate potentially interesting roads, waterfalls, scenic spots etc.
