Can add state parameter in httpx.ASGITransport?

[Provinm]

recently i am making a TestClient based on httpx.AsyncClient, like what starlette have done

my raw code is

class Requestfactory(httpx.AsyncClient):

    def __init__(
        self,
        app: ASGIapp,
        app_state: t.Dict[str, t.Any] | None = None,
        lifespan_on: bool = True,
        base_url: str = "http://testserver",
    ) -> None:
        self.app = app
        if not app_state:
            app_state = {}
        app_state.update(self.app.state._state)
        transport = httpx.ASGITransport(app)
        scope: Scope = {
            "type": "lifespan",
            "asgi": {"version": "3.0", "spec_version": "2.1"},
            "state": app_state,
        }
        self.communicator = ApplicationCommunicator(app, scope)  # type: ignore
        self.lifespan_on = lifespan_on
        super().__init__(base_url=base_url, transport=transport)

the question is there is no way to set state in httpx.ASGITransport

so i have to re-write a ASGITransport class, but only add a state parameter.

class ASGITransport(httpx.AsyncBaseTransport):
    """
    Add state support to httpx.ASGITransport
    """

    def __init__(
        self,
        app: ASGIApp,
        raise_app_exceptions: bool = True,
        root_path: str = "",
        client: tuple[str, int] = ("127.0.0.1", 123),
        state: t.Dict[str, t.Any] | None = None,
    ) -> None:
        self.app = app
        self.raise_app_exceptions = raise_app_exceptions
        self.root_path = root_path
        self.client = client
        self.state = state or {}

    async def handle_async_request(
        self,
        request: Request,
    ) -> Response:
        assert isinstance(request.stream, httpx.AsyncByteStream)

        # ASGI scope.
        scope = {
            "type": "http",
            "asgi": {"version": "3.0"},
            "http_version": "1.1",
            "method": request.method,
            "headers": [(k.lower(), v) for (k, v) in request.headers.raw],
            "scheme": request.url.scheme,
            "path": request.url.path,
            "raw_path": request.url.raw_path.split(b"?")[0],
            "query_string": request.url.query,
            "server": (request.url.host, request.url.port),
            "client": self.client,
            "root_path": self.root_path,
            "state": self.state,
        }


        .......

so i was wondering if there's a chance to add state in httpx.ASGITransport
