I would like to be able to add levels to the approval process. If I have two people review and they approve, I would like to more that document to level two approval without having the original approvers re-approve. I don't want to remove my approves because I don't want to lose the approval, but if I add a new approver and update the version, everyone has to approve again. I want to close one level, maintain the approvals and request a second level of approvals.
