Assign Users to Teams Automatically?

Hello.

I'm using Spark for an app that could have many Users per Team, so having the initial Owner invite everyone by hand is not practical. I also don't want people from the same company (i.e. with same corporate email domain) to establish multiple "Teams" (accounts). What I want to do is:

• When someone registers with a particular corporate email domain, create a Team for that domain and attach the User to that Team as an Owner

• When someone else with the same corporate email domain registers, do NOT create a new Team - assign the new User to the existing Team associated with that corporate email domain as a Member

(I realize I would have to disallow common public email domains like gmail, etc, and also verify email addresses, etc).

Is there a good / right / easy way to do this with Spark?

Thanks.
