F1-F12 keys Help?

[IIIXJokerXIII]

I can't disable the F1-F12 keys in the game.  If anyone knows how I can disable these keys for this game would be a great help to me.  I have a Logitech keyboard/mouse that has F keys that can't be unbound and it is a nightmare playing this game on older gamepads that use F1-F12 keys.  If there is no work around does anyone know where I need to post to ask if they can add this ability to disable the F1-F12 keys in a future update?

Thanks for any help
