1. Is this request related to a challenge you're experiencing? Tell me about your story.

I need to provide the AI with a substantial piece of information in each request within a conversation. This information is only relevant to the current request, and to prevent the conversation context from becoming excessively long, I have decided to place it within a variable in the prompt. Consequently, I require the capability to overwrite the variable value in the prompt across different requests within the same conversation. Maybe it is a good idea to provide a bool parameter in the request to control if this request will rewrite the variable value in the prompt.
