When I want to duplicate an assisit message, I usually do so because I want the same (login here) message to show at specific URL's or subdomains (and not everywhere). For instance at the database homepage and the publisher product site, or on the page with the free, limited service. Now I can't do so, because I have to enter a start and end date, save, activate, reopen to remove dates and save again.
I think it would be better to clear the URL field than to force a start/end date.
