Changing Account name?

I just started a 2nd account under my battle net to RAF up a couple characters. However, when adding the CD keys, it never gave me a chance to name the account and just listed it as "WoW1" in my battlenet account.

I'm wondering if there is any way to change that name, or if it's "WoW1" for anyone that adds keys to a battlenet account?

It's kind of a silly question, but I have mild OCD related to naming and will spend a lot of time reorganizing / renaming books, folders, dvds and the like so it bugs me that one of accounts has a real account name (started prior to battlenet) and one is just a number.

Heck, even if i can't change the new account, maybe I could get the old one changed to "WoW0"? that would work too :)
