Reality Factory

I was wondering if that could be made:
There is the: Which defines how far can a weapon be zoomed,OK but can I make something like the opposite of that like minzomamount = X so when you start zooming you don't start from 0 you start from let's say 5 (minzoomamount = 5) because now when you press/click the zoom button you have to wait the zoom level to rise from 0 to 8 for example and I want when I click the zoom button the zooming to start from 5 and stop at 8 so I'll only have to wait to rise from 5 to 8.
