Not quite sure what you're referring to. At a guess, I am assuming you applied a scale to the model, and are confused as to why the boobs and ass aren't scaling correctly.

You need to right-click the model in the Animation Set Editor, then go Utilities -> Bake Procedural Bones. This will stop them from jiggling, but they will scale correctly.

If you are animating, then what you can do is once you are completely done with your animation, you can go to Utilities -> Enable Procedural Bones to turn the jiggle back on, and then immediately Bake Procedural Bones again to bake down the new jiggle animation while still scaling correctly.
