I'm not sure why resaving them from Poser didn't work for you. Unless you mean the presets specifically. If you load and save each piece in Poser as a new prop, they should have the morphs in them when loaded in DS. The preset styles will still reference the original files without the morphs in them so they won't work, but the individually saved new pieces should work with the morph dials. Before you save them, make sure the dials work in Poser. I'm wondering if the PMD files weren't in place when you loaded the pieces?

As for exporting as a CR2 item (though I don't think that will work), if it asks for a skeleton, in the scene tab, select the piece, then go up to the little drop down and go to Edit --> Rigging --> Convert Prop to Figure. You can use whatever weight mapping you want to.
