I have found it would really help smooth out my landings if I could turn off autobraking after touchdown using buttons on the joystick instead of going to F10 and resetting.  I've tried to program my Saitek joysticks using the FSX "Settings" to use 2 switches to increase or decrease the autobrake settings.  This works fine on the FSX generic aircraft and several addons, but I can't get it to work on the CS 757.  

Does anyone have any ideas how this can be done?
