Apply Scale to Bounding box?

Is there a way to apply scale to a bounding box when you scale an object? I know that you can do it to Scale X,Y,Z by pressing Ctrl+A and reset it to 1.000. Is it possible to scale the object and reset the bounding box back to 2.000? I am doing it for a large environment scene and small bounds of the character mess up the physics and collisions.
