Decided to give this a try, and it was pretty interesting. Using the Mavic 2 Zoom and CS, I went into the CS settings / Launcher Settings, Clicked the DJI Go drop down, and selected DJI Pilot, exit out and booted drone and system as normal, when DJI GO 4 starts, I click exit and select DJI Pilot. It worked perfect. Pilot is a professional pilot app and does not have a lot of features you might be used to, but it offers very precise control of the drone, on screen GPS, and WAYPOINTS. Both route created on the map and fly to GPS points, and the ability to save them and re-fly latter. It offers multiple actions at each waypoint, as shown on the screen shots here. Also, I was able to land, exit Pilot and switch to GO 4 without rebooting.

Worth a look.

Cool! Thanks for sharing it!

Thanks for sharing, I gave it a go today and it worked great... no excuses for DJI not adding waypoints to Go4 any more.
