I have a large application with many relationships to manage where I think vuex orm could speed up my workflow. I searched the documentation to try and understand what is currently possible, below are my questions:

My use case falls under a circumstance where the user goes through complex interactions, which may result in additional modules (components, store modules, etc) being loaded in under the resulting context.

Is there a method to register & load additional model & modules with vuex-orm after initial load?

Additionally, are all vuex-orm modules "flattened" under entities?

entities/elements/earth,
entities/elements/air,
entities/elements/fire
vs.
entities/earth,
entities/air,
etc

Thank you.
