Waypoints aren't a feature exclusive to the DJI Mini 4 Pro. They're also available on the DJI Air 3 and the DJI Mavic 3 (as well as the classic and pro versions), among others.

In anticipation of a long road trip, I searched the web for a list of Buell and Harley-Davidson Dealer waypoints that I could load into my GPS. Having found none, I decided to create them myself.

Waypoints even show up in embedded routes, so anyone you share the route with can see all of the added info, too, helping them plan when joining or replicating your ride.
