How to fully "explode" an assembly (subassemblies and all)

Hi,

I'm trying to create an exploded view in a drawing.  The problem is the model is made of subassemblies that are mated together with rivets, so I can "explode" everything down to the subassemblies, but not the subassemblies themselves.  I have gone to the individual subassemblies and created exploded configurations with those.  How do I incorporate that into the final assembly?

Thanks,

Brian
