Is there a way to transfer Game Center data from one account to another?

My appleID was created way back when it didn't use email as the ID. When Game center came out, i created a different account using an email(A) for game center. Now with iOS5, i was forced to changed my main appleID to use an email, thus i changed the game center appleID to a different email(B) (which i plan on abandoning) and use the email (A) as my main accounts ID.

Problem is, all the game achievements and stuffs I have obtained is associated to email(B) now in the game center, when i use email(A) which is now my main account, it is treated as a new game center account. Is there anyway i can transfer my data over?
