Arnold procedural SOP and reading attributes from packed prims exported as ASS

As the topic says, I'm trying to wrap my head around how and what you can do with the arnold procedural, loading an exported ass file back into houdini. if I just have unpacked prims, everything works as expected, I can use a normal shader network and reference the attributes inside. I found the page on how to add extra attributes on the SOP node itself, but im also told that the arnold procedural sop actually auto loads all available attributes inside? 

 

Anyway my real problem is when I have packed prims or packed agent prims that I export, they export fine, load in fine and render super fast! but I don't seem to able to access the primitives inside.. like if things are still packed and arnold can't see it?  is there a "correct" workflow here that I am missing?
