A much less painful way to do this would be to conform the MFD to your figure,  use all the morph dials you want, then export the MFD as an obj. When you reimport it, all the morphs will be intact, and you can now clothify it. You may then want to open the Edit Choreographed Group or Edit Constrained Group and add a few anchor points between the shoulders (where no one will see them), which will keep the torso portion of the newly dynamic cloth in place through even the most violent contortions.
