How to grey out a component in a drawing (change appearance)?

Hi Guys,

I have a nexploded view in my drawing and I would like to grey out (color in grey) just one of a component of the exploded assembly. I know I can change the layer of the phantom line but I would prefer to grey out the entire component.  How can I do that, the appearance option is not available in the drawing...

Thanks,
