Suggestion: User edit UPC/EAN

Hi,
I've noticed a significant number of games with missing and/or incorrect UPC and EAN codes, largely because people are simply dropping the leading zero from the EAN and plugging that in as the UPC, or vice-versa. Would it be possible to add an option for users to update this information?
