Today, the review date is set at the organizational level, meaning all docs uploaded to the content library must follow this one setting. The request is that there is the option for a review date to be set at the individual document level. So, when you are uploading a doc, and completing the fields, one additional field is the option to create an expiration date. This means once this date is met, that source doc is no longer accessible. If too much work to make in inaccessible, then the date at least is set to review it. Either way, there needs to be a date at the individual doc level not just the organizational setting level.
