Categories for custom pages

I think when making or looking up custom pages there needs to be a way to give them categories. Not saying the linking needs changed. Just stating a way to keep custom pages easy to find.

Like say we can make and delete categories so if I am making custom pages based on games I can make a category named games and when I make the page I can put it in that category. So when you have a bunch of custom pages you don't have to dig for them, Just pick the category and it will bring up a list of pages under that category. If you make this system make a default and when someone uses update all pages are under default till they make a category and put the pages in them.

Hopefully someone understands what I am saying. Sometimes I explain things and it doesn't make good sense. And hope other people think this is good ideal.
