hey i have a question( first of many i might ask here so bear with me for a few days) so i have been using the query engines for querying gpt and i have used both the sub query and multi query functionalities and they work splendidly but how do i use these very engines but be able to add context to lets say the chat gpt bot before querying it. i have a pretty complicated setup with csv and pdfs with information to be queried. i may need to add some context for few shot learning to the bot to instruct chatgpt it in the way it should answer the queries or even pass information to it.
