Radio Calibration

I have an airplane with Pixhawk and just started using channels 9-12. The Mission Planner has no provision for calibrating these channels. Am I missing something or will I have to wait for a future update?

.

what receiver/setup are you using?

I have a Futaba 14SG radio with R7008SB receiver. I get 12 channels output from the Pixhawk ok it’s just that I don’t how to do the calibrations for channels 9-12. Is there an option to display these options on the Radio Calibration page?

I am using 3.0.3 airplane firmware.
