If I understood your question:
in the project downloaded from kevin's site
the Default_Routines() function in the user_routines.c is commented
uncomment it (where it's being called) and edit it at the bottom of user_routines.c
you decide what pwm is for what joystick axis at that file too.
If I didn't get your question right, forgive me and ignore the answer
