Games Explorer -Is It Possible To Add New Categories?

So I recently got a new computer and this is my first time using Win7. I've discovered the Games Explorer thing, which I feel could be really useful for me if I can manage to do what I'm trying to do.

Right now, when you look at the window, it shows Game Providers and Games, which is fine and dandy, but I would like to make more categories.

Here's a screenshot of something I whipped up in paint, if it's not clear what I'm trying to do - https://i.imgur.com/hAzaG.png

I want to add more categories like PC, SNES, GBA, etc. to sort the games better, but I'm not sure how to go about doing that, or if it's even possible. I've searched, but haven't found an answer.

After looking even deeper, it seems it would take a massive amount of effort to do this. Even after making the categories, each game would have to be individually modified to be placed correctly. Ah well...maybe in windows 8...
