I'm not replaying the game to get the badges I already have to show up....

I would like a manual command that just compares what i got to gamecenter and updates accordingly

Also....add all badges to GC last time I looked it supports a small basic set of badges

Oh while your at it apply this same request to the steam version cause ill want my badges there too! :D

... and Google Play Games.

Some of the platform badge systems work quite differently from one another. In some cases, I don't think we can just "update" it with your badges. But, we will re-visit all of that, particularly with Steam.
