Ah, so it sounds like an infrequent thing? In that case, we might better be served with a simple Actions -> Edit Alert Message menu option in the Items Out and Item Status and Holdings Maintenance interfaces. Have that wrapped in a specific permission and staff won't need to go through the heavier Item Attribute Editor.
A bit off topic, but has there ever been discussion of making a copy alert checkin/checkout specific? Our self-check machines trip over alerts on checkout. Luckily we really only use them for checkin processing, so I have a kludge that just disregards them on checkout. A much more elegant solution would be an option to make them applicable on checkin, checkout, or both.
