Views: exposed filter returning nodes where content taxonomy field term is a child of filter value term

Issue Summary

Let's say I have a taxonomy called Location, which is a tree of countries with provinces under each country, and cities in each province. I have a content type with a taxonomy field, but for most nodes the value is a city. For some it may be a province.

I want a view with an exposed filter on that field, but if someone selects a province, any nodes which set the term to a city in the province will also be returned. Right now, only nodes which set the term as the province are returned.

Is there a way to do this? Can regular Views + Taxonomy do this?
