Sometimes I set up parameters and system message for a particular chat about a particular topic. Would it be possible to have an option to reset the context and continue within the same chat? This is effectively the same as starting a new chat but I would have to reconfigure the parameters again. Moreover, I may want to refer to some parts the conversation so far when refreshing the context and being within the same chat page makes that very convenient. If this were to be implemented, I suppose there would need to be some additional logic for showing the estimated cost so far. Perhaps when the context is reset, the app could remember the cost so far and then start calculating for the new context and keep adding to the previously accumulated price.
