Not able to display items per zone on wow.allakazam.comFollow

When I played Everquest, I used to search for all items that drop in a certain zone a lot. I also often used the "List per zone" option, because it also displayed the mob that dropped it in the same table (and using advanced search didnt).

However, wow.allakhazam.com there is no such option at all. Just a moment ago I wanted to get a list of all items that drop in Molten Core, but I can't seem to figure out how to do that and have thus concluded the function isn't there.

I'd really really really like to see that function back. If this is now a premium only option, I'd at least like to have a greyed out page so I don't get confused :)

I'd post this in a diffirent forum, but I've looked around and there doesn't really seem to be a forum for general site feedback, my apologies if there is any after all.
