Trending Analysis in Email Subscription Report

I've subscribed to get the email subscription report on a weekly basis. As of now, I just see the stats per email such as sent, delivered, clicked, unsubscribed etc. It would be helpful if I could see how the results for this week compared to last week (some sort of trending analysis, green/yellow/red gradient of some sort etc). Right now, I just see the numbers and they don't add value until I do some more comparison and analysis.
