Getting Unique Visitors from US traffic only?

Is there anyway to get US unique visitors numbers from google analytics.?

I see that there's a obsolute unique visitors which displays global traffic, but i am only looking for US unique traffic #s.

If I narrow down using benchmark, I see United States traffic, but in "Visitors" not "Unique visitors"

Thank you.

The title of your post is exactly what I'm looking for, did you ever find a solution?
