Need help transferring a game between groups

I was just wondering if there was any fast way to easily copy a game over from one group to another.

Copying the game itself is simple enough, but some assets, such as audio and animations, seem to require some level of authorization to be used before being able to be used in other places.

Is my only option just to copy it over, and then re-authorize all of the audio/animation/etc. by hand, or is there a quicker way?
