I would like the stamp user (in addition to the creator and editor) to be included on a document as well as file or processing information (e.g. approval in the case of an invoice), so that colleagues can search for documents that they have approved with stamp XY. Although we have the editor name visually entered on the document when the stamp is set (as the name editor, e.g. approved by:), this does not help with a search because the stamp content is not also searched.
