I read online that Dx6 was an acceptable remote for the pixhawk, so I bought one...But the problem is, when I want to set a waypoint they want me to flip the channel 7 remote, but I do not have a channel 7.Is there someway to accomplish this same…

Everywhere I read speaks about using channel 7 to add a waypoint, but I'm using a spectrum dx6  (was on the list of allowed pixhawk radios)Is there a way to add a waypoint without using channel 7?Thanks!
