A UDF and a macro will do the trick.
Sub Props_In_Footer()
With ActiveSheet
.PageSetup.CenterFooter = DocProps("last author")
End With
End Sub
'=DOCPROPS("last author")
'or
'=DOCPROPS("last save time")
Function DocProps(prop As String)
Application.Volatile
On Error GoTo err_value
DocProps = ActiveWorkbook.BuiltinDocumentProperties _
(prop)
Exit Function
err_value:
DocProps = CVErr(xlErrValue)
End Function
