Use a system prompt before sending messages

Proposal

Adding a system prompt option to pre-prompt the model before accepting user messages.

Information about a system prompt

A system prompt is a set of instructions that guide an AI model's behavior and responses.

• System prompts are processed before the user's input.
• They define the AI's tone, actions, and output.
• They ensure the AI's responses are accurate, relevant, and consistent.
• Well-crafted system prompts can improve the AI's capabilities.

I know this can be achieved by sending a message and not printing the output, but I think it would be better to have it as a separate field.

This already is a separate field, called system
