List segments

What I would like to be able to do is segment my list by people who have opened at least one email within a time frame (say 6 months for example), people who've opened two or more, five or more, etc., as well as people who've received (say 10 or more emails) and never opened any of them.

Currently I can select people who've opened specific emails or specific combinations of emails, but I don't see any way to segment out people who've never opened any emails at all.

Am I missing something?  Or could this be a future enhancement?
