Say in those games where you either want your bonuses multiplied by two or ten for example. You press a button, put in the multiplier (fractions if you want to reduce) and it sets all of the bonuses. Also a button to reset all bonuses to default (not sure if already exists).

I think MotD has a script for that?

That's for bonus values being increased or decreased by 1 or remain the same.

I use to multiply all bonus values by X.
