Modelling FBMs for clothing

I'm trying to create FBMs in clothing with a modelling app - specifically, BAT Labs Casual Wear Pack using Truespace. I finally created a successful FBM morph that affects the left & right collar, chest and abdomen. It works but I want to verify that I'm not missing a step or doing anything that will have ill effects in the future. These are the steps I followed:

1. Load the clothing item in Poser
2. Export OBJ with the groups I need ("Include existing groups..." and "As Morph Target" checked)
3. Import OBJ into Truespace, scale up, modify with deformer, scale down
4. Export each group as an individual OBJ (4 of them is this case)
5. In Poser, load morph targets to each affected part
6. Name these 'pbmMorphName' by convention. Or is the 'pbm' a special/reserved name?
7. Dial each individual morph to 1.0
8. Figure > Create Full Body Morph
9. Name this 'MorphName'
10. Reset individual morphs to 0
11. Add to Library

Like I said, it works fine and the process isn't too cumbersome. Is this method going to cause any future problems? Is there an alternate or simpler method? Thanks.
