Merging state with parent graph when jumping to a node in parent from subgraph, how to update the state of parent graph?

[rohitkhatee]

When I do this

return Command(
        graph=Command.PARENT,
        update={
            "reasoning": input.get("reasoning", []) + [reasoning],
            "steps": input.get("steps", []) + steps,
            "user_interactions": user_interactions
        },
        goto=nodes.USER_INTERACTION_NODE
    )

it first updates the state of current subgraph, then jumps to the node in parent graph, but parent graph state remains as is. Is there some way langgraph supports updating the parent graph state before the node it jumped to executes?
