Calling Out The Parts

I think I might know the answer to this, but just want to make sure that there are no other ways to do this. I have one part (which I have attached) that is composed of other parts in the same file. In real life it would take ten parts to put this together. In SolidWorks 2010 do I have to create a separate part in order to have each unique part show up in the BOM? Or is there a way to call out each separate part with its own properties without having to draw each part separate. I hope I make sense, thank you.
