Sub categories and groups

It would be great to have more granular control over storing chats.
I could have a project which is an overall piece of work, where I can share generic information about the bigger picture - but then a subfolder for comms, and another for guidance documnts, and another for ideas, etc.

At the moment they are kept as separate chats, but an additional folder structure would make this much better - responses from chatgpt could be specific to the task in hand, but also reference general information, rules and guidance about the bigger project that it is part of.
