Adding System message option to question & answer chain ?

When debugging the question & answer chain, I can see a system message is sent containing some instruction plus the result from the vector search.
But instructions are in english, and very simple and I can’t tune the behavior of the AI Agent.
I tried to change the human message with some success and fails. But wouldn’t it be simpler to have the same possibility as in AI Agent to define the system message ?

Information on your n8n setup

  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

By the way, looking into the code, I saw this predefined system message is handled by the library N8n uses so there’s almost no chance this behavior will change.
If I find another way to setup this workflow I will share it.
