Here’s a variant that doesn’t require you to type any names, plus you get super efficient packed primitives.
Basically, you just pack each set of primitives (i.e. one for each sphere, torus, etc) first, then merge them all together in a Merge SOP. Now you can just grab them as individual primitives inside VEX which is incredibly convenient. It works because each packed primitive has the @path attribute to indicate where it came from that you can use directly in the @instancepath attribute. Hopefully the attached image should show up below.
