Revision Table Default(s)

When we release a drawing to Production, the INITIAL release of the drawing is DASH ("-").  When we insert the first revision row in a drawing, it defaults to A (or ONE if using numeric revisions).  Is it possible to set up the table in such a way, that when the first row is inserted, it starts with a DASH ("-") or ZERO ("0").

Clear as mud on a foggy day?
