Rigid Body "Dynamic" and "Animated" states

Hi, I am getting familiar with the simulation side of Blender, and I am trying to set the Rigid Body “Dynamic” and “Animated” states for a group of physics objects in a scene. If I try to edit the Rigid Body properties with all the objects selected and the ALT key held down (or using copy to selected) works for some properties (Like collision type, or friction, etc) but the settings for “dynamic”, “Animated” I can’t seem to set properties across the selected objects in any way. How can I edit these properties on a group of objects and have those animate? I may be missing something basic in Blender (I have used it now for about two years, and come from a max/maya background), But I can key these tracks on any individual object, but I can’t figure out how to change these specific keys for a large group of objects. Any help would be greatly appreciated.

Thanks in Advance.
