Okay so to update. I have been working with BMWNA and was told the divider can be retrofitted. After I explained my issue to them they agreed it was not articulated well in their marketing brochures and order form. They talked with my local BMW dealer and agreed to give me the parts for free and I'd have to pay for labor of $138. I thought that was great and now only waiting to hear back from Kuni BMW for parts availability and set an appointment. I'll post another update and photographs when the install is complete.
