How would I add new collections after waterline is initialized?

[JemiloII]

So what I am wanting to do is make a dynamic service. While my application is running, a user can do crud actions against models that new services will use. I love how waterline can connect with many databases, however, I am not sure if after I initialize, if I can simply add more collections to it, or even the best way to export them. The initialize function seems to just have a callback to it.
