Updating filters

A question for the site administration. Is it possible to add continent selection to the search filters? Example: I want to see a list of fantasy coins that are specific to Africa, but I have to search through all the coins listed or manually search for each territory.

I always wanted this on the filters

But I understand would be a huge work to select each issuer for the correct continent, and many will be from more than one, like the large old empires and kingdoms. And of course eurasia/isles are also not simple.

But would be a huge improvment, sometimes I want to search only european medieval coins without scrolling lots of pages of indian/asian coins.
