yes it is possible, you can have a code in each of the red bits here:
set gpad_buttonsConfig "Put Code Here"
set r_gamma "1"
set snd_volume "0.8"
set input_invertPitch "0"
set input_viewSensitivity "1"
set gpad_sticksConfig "Put Code Here"
or you can have 2 .CFG's in one space, but its complex and difficult. I posted how a while back, if you search you will find what i posted.
