Ability to rearrange UV Maps.

Please give us the ability to rearrange UV maps(move up and down).

I'm making models for a game that requires multiple UV maps. If I make UV0, UV1 and UV4, and later I want to add UV2 also, it will end up at the bottom of the list(naming is required by the game's blender export addon and the game)... would be great to get same kind of up/down arrows for this as we get for materials in the material list.
