Reusing a block and making it into a part.

Hi All,

I am playing with Top-Down design and understand creating blocks, etc and making parts from them but if I make a block into a part in a layout assembly and I have used that block in multiple places, is it possible to replace all the blocks with the newly created part? Its the behavior I expected but it didnt seem to happen.

Regards,

Tony
