First off, I've turned off Unassigned in my project as tickets can get lost.
Issue: Whenever someone creates a ticket, it gets automatically assigned to me if they didn't specify who the assignee is as I'm the Project Lead. I tried using Automation to reassign the ticket to the reporter if it's not specified, but it doesn't trigger it because we don't allow unassigned. There's no criteria that says "Automatic" either, so I'm at a loss on what to do other than allowing "Unassigned".

I only want the ticket to get assigned to the reporter if one is not specified.
