Proof Reporting - Quantity of Comments by User per Proof

[#1]

Our marketing team is in need of a way to run a report using Proof data to capture the number of comments left on a proof by each reviewer.

This would provide insight into how many comments were provided on a proof without manually going in to each proof to count.

We are looking to use this data to inform us if a reviewer is truly needed on the review based on volume of feedback.

I checked with Support and this is currently not supported.
