I have done some talking with a couple of my team members on this. You are correct. The email status search, while it has search criteria and columns for additional email fields, the status column is reflecting Email 1. I am sharing this in a meeting I have with one of our developers, as I see exactly what you are needing. I also, have never been asked a question on this personally, so I had to do some testing of my own.
I wanted to see if I could share the link to our official product feedback form, and have you head over to share some examples of how you would utilize this, and go over some of your basic needs for a report like this @ https://infusionsoft.com/tellus
Let me know after you have shared, because I want to have our Customer Experience Manager pull the feedback for me, so that we can share your use-case with the team that works on our reporting functionality.
(While we do not have a native out-of-the box report to pull this style of data, this may be possible via the api… not sure how much you dabble with the Infusionsoft API)
