Ember JS: Nested api routes

I need to perform a GET operation to the following HTTP end point:

/api/v1/users/security_questions.json?memberID=1234

I've been told that Ember JS does not support a nested endpoint like users/security_questions and rather I would need to do:

/api/v1/security_questions.json?memberID=1234

Is nested API routes supported? If so, how do I implement it in my Model?
