Feature Request: Profile Models

[evantahler]

Is your feature request related to a problem? Please describe.
When importing Profiles, I want to be able to have a few types of Profile Models, for example, "Rider" and "Driver" in a Lyft-like car-sharing application. The "Rider" and "Driver" Profile models might not have the same Properties nor would they be in the same Groups.

Describe the solution you'd like
When creating a Source, I want to choose which type of Profile Model it will be importing.
