Is there a Smart Objects "Make Unique" Button?

I am looking for a way to make a copied smart object unique (for example, 3dsmax has an button for object instances to "Make Unique" which basically unlinks it from the original object it was instanced to. I know I can copy a smart object, etc. etc. But I don't want to have to copy anything. Is there a "make unique button" for Photoshop for smart objects? If so, adobe really needs to add this functionality
