audit-viewer serial number?

How can I specify the serial number as one of the audit-viewer columns? I know how to add columns, but I think since the SN is not named it may not be in the available columns list. That or I missed it. I can see the SN if I double-click on the event, as part of the ID in the top of the "Event Details" window, however I'd like to be able to see the numbers in a column.
