Additional Bucket Seat(s) in Cargo Van?

Looking at the seat layout of the Passenger Wagon version, I see that it can contain a single bucket seat in the third row end. Does anyone know if I can buy and install the additional bucket seat in the cargo version in the same location?

I need a seat for an additional 3rd passenger but buying the extra bench seat will not work because I need to leave the center of the van open for long cargo. So I need to add an additional 3rd bucket seat. Adding a 4th would be even better.

I hear there may be new seating options for 2016 but that hasn't been confirmed.

Thank you in advance for any help with this. I am excited about joining the Transit community.
