Automatically Link Custom Object to Ticket

Hello Zendesk Team,

Is it possible to link an existing custom object to a ticket based on the requester fields using triggers or something? For example, I have a custom object called "city" and its linked in the user profile under a "city" user field. Would it be possible that once a ticket is created, the city value that is in the users "city" field in their profile gets added to a "city" field inside the ticket?

What I want to achieve is for example save the city that the user had when the ticket was created, but I want to avoid it being a manual field if we already have that relationship inside the users profile.

Thank you!
