Any way to increase the maximum CAS values?

Is it possible to force larger breasts/ass or does it require a completely new body?

yes there's a mod called breast augmentation for breast they have a bunch of different shapes and limits to choose but only install one as for butt I know there mods for it that use default body but the problem is it can make the whole lower body shake from my experience.
