BentoML

is there anyway that I can access the flask app that is being created in the Bentoservice and add a middleware like the following
```application = Flask(__name__)
application.wsgi_app = PinPointMiddleWare(application, application.wsgi_app)```

<@U01BMCJ29LN> <@UQF2L5GQ0> can you please help?

I see that in ModelApp class under bentoml.server.model_app.py  we have
```for middleware in (InstrumentMiddleware,):
            self.app.wsgi_app = middleware(self.app.wsgi_app, self.bento_service)```
even if i can access the ModelApp object which was initiated during runtime, I can extend the middleware for flask
