Tabletop furniture on half partitions

As the title I would really like to be able to put tabletop items on the half partitions, I kinda assumed you would be able to.

That was one of the first things I ended up putting in my personal room. Was disappointed when I couldn't set anything on it. Other than not being able to set anything on it, why is there a Riviera design only? What about the Glade and Oasis styles?

I, too, was wondering why there was only one style of half-partition. There are Riviera models of particular things like the Doormat and the half-partition, but there are no Glade and Oasis variations.

I wonder if those are to come later on...
