Does any one know if there's a way of creating a true single file dumb solid without retaining all the additional references using SW?

I've imported a Parasolid camera body into SW2016 & it contains 622 Solid Bodies & 181 Surface Bodies - that's a lot of referenced bodies!!

Even if I re-export the part out (Parasolid or STEP) & re-import it back in the referenced bodies are still retained. I've even tried inserting the camera body part into another blank part, breaking the link, exporting the part again (as a Parasolid) & opening it & the referenced bodies are still listed.

In Autodesk Inventor you can simply use Shrink wrap or use Derived Component, breaking the link & you are left with a true dumb solid. All original references that were used to create the file are removed as they are no longer necessary. Plus the file size is drastically reduced.

I am missing something or is it impossible to get SW to remove the part references & make a true dumb solid?
