What figure are you talking about? If it is a Poser7- figure (which includes Victoria 4/Michael 4 and their generation) there is a poser python script called dyn2morph which will convert the drape in each frames of your animation to a morph and set the morph correctly. Then saving it as a pz3 will allow you to just open it in DAZ Studio. (Note also works for a still.) The last place I saw the script was on CarraraCafe. 

This is not a method I have tried with DSON Importer for Poser, for example, Genesis or Genesis 2 (Male or Female) so I don't know if it will work. I know it will not work with Poser figures created using Poser rigging after Poser 7, so no Roxie, or Miki 3, etc.
