Currently we have 1 case record type that is restricted to supervisor staff and above (case object is set to private with criteria based case sharing rule to allow visibility to public group that contain all managment staff) . This case record type has the ability to upload a file however of those users who have access to this case record type, there is a subset of users who would like the ability to restrict visibility of files even further (so that only the subset and executive management team have access) to this case record type if they choose. How can I accomplish restricting visibility of sensitive/private files that are attached to this case type?
