Hi James,

you could add a menubar with your own button. A little macro could than
add a set of categories to the selected Item, e.g.:

With Application.ActiveExplorer.Selection(1)
   ' This would *add* your set:
   .Categories=.Categories & ";MyStandardSet"

   ' *OR* this line, it would *replace* all existing categories through
your set
   .Categories="MyStandardSet"

   .Save
End With
