Forum Option: Sort by Category

I believe there should be a forum option to sort by category. Does this capability exist at present?

Currently, when I go to, for example, the Multiplayer forum I have to look at all the multiplayer topics for all the Halo games. There are topics for Reach, Halo Anniversary, Halo 4, etc. all intermingled. What if I’m only interested in Reach topics? I think it the addition of “Category Select” option, much like the one between the subject and body of new posts, would make browsing much more user friendly.

My apologies if this is already possible and I’m simply overlooking the option. I’m simply hoping to make the Waypoint forums better for all.
