I just let DIM do it’s chaotic best and then go to finder and move the files into sensible folders like “V4 Clothing.” DIM almost always gets it right with Genesis 2 products, which fall under the DAZ file structure of people, e.g. Genesis 2 Female/Clothing. You can find instructions elsewhere on how to convert DSON products to Poser native ones, as well as “DS only” products that you export as cr2’s from DS. Once you do the conversion, there is no DSON lag at all.
