API access to editing System Prompts

It would be great to be able to GET, DELETE and POST (update) the Prompt for a Chipp chat. If I edit (at my end) master snippets of prompt instructions that are common to many Chipp apps, but then other parts of the prompt vary from app to app, then I can calculate/compile each prompt from its components and send it to Chipp. This would allow the updating and managing of many prompts at once, so that all chats benefit from prompt improvements.
