Admin Forum:"Contributing to the wiki every day for .. days" achievement

Hello. I want to modify achievements like "Awarded for contributing to the wiki every day for 5 days!" (original name "Key to the Wiki!") to count not days in a row, but every different day a user made an edit. I don't want to force anyone to edit my wiki just for the sake of little fun of having some badge, badges should be earned passively and should not be specifically worked on in my opinion. The "every day for 365 days" badge just makes no sense to me.
 * Unfortunatly the badges are hard-coded, so there's no way to change them --  Random Time  16:40, November 15, 2012 (UTC)
