Is there any way to set the ISBN identifier to N/A or similar to indicate that I have checked the book and there is no ISBN number available? I would like to be able to distinguish between "no ISBN number set" and "I have checked and no ISBN number is available"

The reason is that when doing library maintenance, one of the first things I check is books that have no ISBN number set as I use the ISBN to eliminate duplicates and ensure correct metadata. The problem is a have a number of books that have no ISBN (eg it was published before 1970) that show up whenever I filter on isbn:false.
