I have External Customers allowed to self-register but restricted to a list of domains, and I have a list of Organizations named by the legal name of the entity with an attribute called "domain" that lists their email domain.
I saw the guide on using automation to automatically add a user to an organization when they create an issue, but it seems like that would create an organization named after their email domain - would there be a way to instead use a smart query (I think that's the term?) to query for which organization has a matching 'domain' attribute then set the organization field of the issue to that?
