Tracking rounds of production/review for external creative review processes

We'd like to see a feature added that makes it easier for project managers to track rounds of creative production, proofing, and review and approval when those rounds are performed externally from Workfront (i.e., a different proofing platform or method other than Workfront proof). There are business cases where a client might require proofing processes to be done on their own system, etc.

In the system's current state, it's been suggested to upload all versions of proofs to Workfront (even though they're not going through Workfront proof) to simply track the number of versions. Another suggestion has been to repeat the production tasks in Workfront over and over again (parent with children tasks, resulting in x number of parent tasks = number of proofing rounds), but that is not efficient or feasible.

It would be nice to have some sort of check-box at the task level (parent and/or children) to tally the number of rounds as the proofing tasks cycle over and over again.
