Forcing a unique email/name/ID

Is it possible to ensure that the user enters a unique email, name, or ID by checking against existing records in Airtable? If the input already exists, notify the user accordingly.

Without running an automation, there’s no way (yet) for us to do this.

Of course the Noloco user table enforces unique email addresses, so you could maybe make the users on that table and then use a workflow to push them to Airtable if they’re unique?
