Track Google Analytics Goal Conversions for Hustle Opt-ins?

I see that Hustle tracks conversions for the opt-in forms. Is there a way to integrate that to track goal conversions in Google Analytics? For example, is there a way for it to generate an event that I can track?

Or, are there any other goal configuration options that will work?

That would be really helpful, because it let’s me see which sources are generating opt-ins (e.g., Facebook, Google, etc.).
