Can I transfer a pack (MLB® The Show™ 16 10 Standard Packs) to a sub account

I redeemed a code from an email when we purchased MLB® The Show™ 16 10 Standard Packs.   I dont get on the PS4 and thought my son would be able to use it when i logged in and redeemed the code.  I guess he signs in with a different account so he cant get to the packs.  Is there a way to move the packs to his account?

Thanks
