Updating expiration date for a domain

We are about to fully migrate to FRED from our home-made system. Now, what we want to do is to create domains in FRED according with our expiration date information. But there is one problem: create_domain takes the date from the system, so if I use create_domain today for say, a year, it would create the domain with an expiration date of 6th. June, 2012, which is what I don't want (suppose that that domain was created, say, 6 months ago using our home-made system, the expiration date would be 6th. January 2012). One solution would be to modify the ex_date field in the domain_registry table according to our original information. Does this make sense?. Is there any cleaner way of doing this?
