Sportsman 850 Touring Rear Seat Question

Just picked up a 2016 today. I have been a dirt bike and snowmobile guy, this is my first ATV that I have bought.

What are you supposed to do with the gaping hole left from removing the rear seat? Is there a cover or box or something that can be had to fill the hole in? I was thinking the longer wheelbase of the Touring might not be a bad thing for 1 up riding even, but it would be nice to take the seat off sometimes.
