Report on Campaigns Making Field Changes

I know that I can see which smart campaigns interact with a field under field management. But I'd like to see more detail, specifically on which campaigns entered a specific value in a field. In a complicated instance with many, many smart campaigns editing a particular field, it is difficult to track down what exactly is causing a specific edit to be made.

It would be awesome to have some sort of report (like the Campaign Activity report type) that allows filtering by flow steps and displays the campaigns that complete/have completed those flow steps.
