Custom morph Additive instead of Full Change

cropcirclesstudio

Is there a way to make a morph an additive to other morphs instead of changing the entire thing? I mean there are moments where you want your cloth to just add a morph to it instead of the cloth changing entirely. If that makes sense. When I use morphs say on a character to fix clothing issues it just changes everything to that morph when I just want it to add to the others. Pretty sure I probably just skipped by an option without noticing probably but I am going to make sure just in case.

Let me see if i can clarify here to make sure we're on the same page.

You want to have, say, the hips wider, but not the base character morph applied to the clothing?

right path or way off?
