Hmmm ... Full body morphs don't cancel each other out, no. For example, you can create a Vicky character that is part Fairy full body morph and part Barbarian full body morph. They mix together. OK, let's say you want to create a body for Vicky that has smaller breasts, a narrower waist, larger hips, and shapelier legs. Dial existing morphs that create that shape, all together. Let's say it takes 10 separate morphs to create that body. After you get the entire body shape you want, you can create the full body morph. Save it under a name that you remember, and the dial appears in the "Body" part. Go back, and set the ten individual dials back to zero. When you go back to the Body and set your custom full body morph to 1, it should look exactly the same as when you set the ten individual dials to their settings.
