Multiple button component skins

Hi,

I have been use a button component by dragging it to the library and then modifying its button states. All this is great but now I want to add a second button component to my application. When I drag a new button component to the library all seems well except there is not another folder of button states for me to modify. How can I use two or more button components and give them all different skins.

Thanks,
