By default, Reviewers have visibillty to everyone in the system. It would be great if we could set up rules to limit that to a specific location, for example. If that person also has an Admin role, that visibilty takes precendence, which can lead to users not being visibile in the Reviewer Experience.
I am running into this right now. We are using Observation Checklists to track our orientation meetings for new managers. Our situation involves department heads meeting with new staff that are not in the same department so we have had to scope reviewers to view all employees so having more control over this would be useful.
