Is there a way to change the scope sensitivity?

I play at a sensitivity that's comfortable, even just slightly too high for my taste. The problem is that the sniper rifle's scoped sensitivity is so low that I am unable to really hit anything at all, I mean, I would have to move the mouse at least 3 feet just to turn a very slight bit. Any help is appreciated.

No you can't at the given moment, the factor is 0.6 and a balance value (henceforth not editable)

There is a working console command to set the sensitivity, right?

Could you create an on-press/on-release binding to issue sensitivity commands, then assign that to the same button as alt-fire? Or put it on a separate button and use Autohotkey to map your right mousebutton to generate an additional keypress

I'm new to the unreal engine and have no idea how to make configs with it.
