You can't do that now, because there are no updated street lists. The list your using (in PA at least) is from late April. And, as you pointed out, you've been out before. 
Late April? Where do you get that from? PA has a dynamically updated database
online. I sincerely doubt they haven't updated their public registration file since April. That would make them worse than any state I've ever dealt with. Most do it monthly, and counties can generally provide you with an instantaneous list.
I sincerely doubt PA is both totally centralized and hasn't updated since April, but if so, shame on PA. (But since most of the nation isn't PA...)
