When binding keys, mouse wheel clicks do not register

As I am changing the controls for intruder, I tried to rebind a key to the middle mouse wheel click, but it will not allow me to do so. No error message or anything, just a flashing box letting me know that Middle Mouse isn't a valid key. Any known fixes, or any in the future?

It works if you center your mouse cursor in the flashing box and then press the MMB. This approach works for all mouse buttons except the mouse wheel.
