@Jeffrey-Kogler Hi Jeffrey, while not specifically a suggestion I've marked this as one, I hope you don't mind. This is because I haven't seen this before and I think it might be a good idea for the future. As others have pointed out, it's currently not possible to use the search function and then add the waypoint after a certain other waypoint. I hope that regardless of this you'll find ways to enjoy the benefits of MRA.
