Hello, I could not come up with something perfect right away. However, You could create different views:
Created by (own uploads)
These views could then be shown on two different SharePoint sites. The users would work through the document web part (that has the correct document library as a source and selected view). The managers can have their own site, with FAQ and other features that are related to simplify managers workload. The document web part in the managers site would be from the same source, but a different view.
