I'd love the ability to permission people/roles from seeing previous versions of a proof in Workfront Proof. For example, we start routing a proof internally and it goes through several rounds of proofing. Now it's ready for the client to see it. I'd love to send the most recent approved version to the client for review but don't want them to have access to the previous versions. They mark that up, edits are made, another couple rounds of internal review and then the approved version goes back to client. At that point they only have access to the versions of the proof they were a part of.
Why is this feature important to me? This would allow us to have one document that spans the entire life of the project but would prevent clients from seeing all of the back and forth that happened to get that piece approved. To accomplish this in the current state we have to create a clean document to send over for client review. When we go that route we are left with 2 unappealing options:
1. Have multiple documents for the same deliverable or
2. Someone has to transfer all of the client markups back to the original document's proof.
