Is there any easy way to use a queryPipeline as a chat_engine()? Do I need to add input nodes to the DAG and manage chat history and condensing as part of the queryPipeline or is there a way to use a existing pipeline to wrap it with chat_engine() functionality?

Hi all, just a quick question, why do we not allow FunctionTool to be used in QueryPlanning here(https://docs.llamaindex.ai/en/stable/examples/agent/openai_agent_query_plan/?h=query+planning) ? Is there any way i can inherit FunctionTool to give it the expected capabilities of a QueryEngineTool to allow this to work?

Do FnComponents auto typecast based on func param types? If not is there a plan or roadmap to include this with pydantic or any other way? Would love to explore/contribute to this if possible @Logan M
