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

Each time when calling agent node, it would always use LLM as the last round to generate final output (unless we set only 1 round is allowed), it may cause too much time waiting, if the agent node could only output the mid-results produced only by tools, it may save lots of time and be more flexible.
