Add airplane model to my Devo F7 preset list.

Hi can anyone let me know how do I add ( step by step instruction) my new Phoenix X EVO 742-5 glider aeroplane to the preset list of models into my Devo F7 transmitter.Most instruction that I can find on the net is meant for Devo 7 but not Devo F7. How do I add the name and do I need to change any settings in the options given eg. Aileron, Elevator, Rudder etc. I currently have my QR X 350 model saved in the transmitter ( presetted for me by the vendor). Thanks to anyone who can assist.
