We are seeing a growing need for built-in Tiered reviews or different review levels and the ability to mark an approver as optional.
Tier 1 Review would be an internal or creative review and ideally, we would be able to automate the next steps. If approved at that point, it would move on to the Tier 2 review. If they required changes, we could notify the project manager as we do now and it would kick into revisions and start that process over.
Tier 2 would be the next level of review - typically this is the original requestor, a marketing strategist, sales manager, etc.
Additionally, we have some reviewers who we deem required and others who it would be nice to hear from but we wouldn't hold a project up waiting for their review. It would be awesome if we could mark reviewers as optional so that if the primary or required reviewers mark it approved, we just considered it approved and can finish the review at that point.
