Allow the option to set automatic daily / weekly knowledge base refreshes, and/or an auto-refresh on the Google Drive folder contents changing.
This would allow us to give clients a Google Drive folder they can add/remove training information (so things like a daily menu special, weekly sale specials, etc), and know that the chatbot will stay current with the latest information.
It allows us to sell the feature, without forcing clients to log-in to the CRM and have to navigate the interface. All they would have to do is manage a Google Drive folder, and we could know the knowledge base would always be current.
