Uploading Illustrator Document with Multiple Artboards to Library

[#1]

During the last Adobe Max, I learned that you can upload an Illustrator document to one of your Adobe Libraries and it will add all of the assets within that library. I could've sworn that if your document had multiple artboards, it would break out those artboards into their own asset. I'm trying to do this, but the library only recognizes the first artboard! Is there something I am missing or did I misunderstand what was demonstrated in the session I was in?

Could you perhaps show your setup and tell us what exactly you are doing step by step?
