Replying to Improving the Sell and Trade forum

Hey guys I was looking through the sell and trade forum and realized that with the exchange rate, buying stuff from the Us can get pretty expensive and to find stuff only from Canada takes a while since you need to check every single profile of the members. So would it be possible to either have a sub forum for different part of the world like regional but only for sale and trade or to have a filter option that only shows members from certain area?
