Is there any way to reverse the scroll wheel? I keep getting messed up by the fact that scrolling up moves to a LOWER numbered weapon.

EDIT:
On a related note, is there any way to get this to work properly with Autohotkey? Because I tried to reverse the wheel with AHK and the script works fine outside of the game, but it the game it makes the wheel not work at all

Settings > Feel > Customize bindings

Scroll all the way down and rebind both mousewheel options.

Thank you
