FILTER by country

so living in Detroit Im less than 5 miles from Canada and get a LOT of Canadian members show up on my search, my whos' on, my randoms.... love the Canadians but it's getting more and more difficult to cross the border (more id required, questioning at the border, etc), would be nice to be able to de-select Canada as a prospect (no offense), and Im sure many of my Canadian members would not like to see so many Detroit area members... Thanks.
