During a call i want to change the flow of the conversation based on the current context. For example: I am creating a customer bot and I am talking to it as a sales person. I want the bot to ask the pricing of the product once i explain the product. Or bot should ask that why should i but it from you? I don't want to pass this in the initial system message. What is the best way to control this?

@Akshat Jain can you share more context.
