Email Group Subscription Status

Given Insight only shows "Global" unsubscribes, the only current option is to work with Segments to see who is unsubscribed at the Email Group level. The challenge from a reporting point of view is that this becomes a very manual process, especially if you're wanting to see who unsubscribed or subscribed as a result of a specific campaign from an email group.

Has anyone come up with a smarter way to get this information automatically by campaign?

Ideally it would be great if email group subscription status changes were shown in reports adjacent to global unsubscribe data.
