The simple answer is no. But the deeper issue is it sounds like you're attempting to use autonumbers in a way that assigns business meaning to them, which most folks who design a lot of DBs would recommend against. Autonumbers aren't intended to carry business meaning (i.e., serve as a data item, such as a meaningful serial number). They are designed to serve a logical function, not a semantic one. They provide a simple and consistent way of uniquely identifying a record in your database (primary key), but only your databse should ever need to know their value. They are generally hidden from the end user. Apologies if I'm off the mark here, but I suspect that what you are trying to do is something you wouldn't want to do, even if it were possible.
