We would like to add the same person to a review route twice in different stages. We have the project owners review proofs in stage 2, but then also need to review again in the last stage after everyone else has reviewed, so they can review other's comments, comment back for clarification or answer any questions.
Why is this feature important to you - Streamlines the process. Currently, the project manager has to reach out to the project owner after the route is complete to confirm there aren't any comments that need to be responded to, and wait for the project owner to reach back out to them when they've had the chance to review again. If they can be added again to the final stage, they will get the automatic email notification that it's their turn again. Once the review is complete, the PM knows it can be routed straight back to the necessary team without any additional steps in the process.
