Stitch Together Multiple Way Point Missions in Mission Hub

No there is not.
Look at this post for a possible workaround:

Reorder Waypoint

Hey folks, short question. Is it possible, preferably in mission hub to reorder my waypoints? I was flyin manualy to best position and camera angle and took waypoints by c1. Now i want to make a nice track around it smooth. But i can’t change the order of my manualy recorded waypoints. I just can add new between them. For example. Recorded order is 1, 2 , 3 , 5 … But i want to fly 3, 2, 5, 1 … Please help! Regards from germany.
