Occurence properties/Reference Parts

Is there a way to change the properties of a part in an assembly so that it shows up as a reference only part and doesnt show up in higher level assemblies? I know that in Solid Edge you can use Occurence Properties and it gives you many options to change including the ones I need. Any one know of any such thing in Solidworks? Using 2009 version
