createCaller Dependency Injection in Middleware ctx ?

createCaller

createCaller

makes it really easy to inject dependencies via anything that's created during the

createContext

createContext

function:

router.createCaller({ someClient: mockClient});

router.createCaller({ someClient: mockClient});

However, some times it makes sense to add dependencies in middlewares that are only used by a subset of the procedures. For example if I had a

twilioClient

twilioClient

that is only used by my

authorizationRouter

authorizationRouter

, it could make sense to supply that dependency via middleware instead of the

createContext

createContext

function.

Is there anyway to inject dependencies into a middleware versus just the root
