Currently the only way to move KBs created from uploading PDFs is to use the bulk manage function that is quite clunky. We have an interface for setting the folder of a normal KB, but for some reason that is missing when creating a KB by uploading a PDF.
It would be nice to see this same functionality for moving KB's between folders when they are uploaded from a PDF just like normal KBs. It is really confusing to have to use a different method.
