This seems like a good product, although it is early.  As stated in some other reviews the lighting needs some work in the refrigerator side.  We have the model GZS22DMJJFES, but have noticed the GZS22IMNES model has additional shelves, one more drawer in the fridge and one more wire shelf in the freezer.  Can these additional drawers be added to my model and what are the part numbers for the additional shelves.  For clarity in the freezer it is the shelf second from the bottom and in the fridge the third from the bottom
