I'd like to do deep dives into different PDF's / books, and then ask questions across those deep dives and create tables. Is this possible? Basically, do them one at a time, and then have them connect to work with, instead of having to load separate chats and use deep dive credits on the same material over different chats. So maybe a file browser where you can use deep dive credits to run deep dive on the document, so you can reference them later and open chats after they have been analyzed in that way.
