Use "Wayponts" in DJIGo4 and when you get to a spot you want to keep, make it either the first waypoint or the last.
Save the mission. The next time you need to head to that spot, fire up Waypoints and start the saved mission.
If you're not near the point when you start, if it's the 1st point it will head there before starting.
If it's the last point, it will stop and hover there.
