Market filter in the Contracts tab

We send message cards to a market and different products to different markets from time to time. It is quite difficult to count which customer is from which market (especially the Northern Ireland since they get shipped from our Irish warehouse and not the warehouse in England). A advanced filter in the subscription contracts section with "country and provinces" would make this administrative work easier. Considering customers cancel, pause and new customers subscribing to the product makes the process even slower for us.
