Default or Form Contact Owner?

Is it possible to set a contact owner for all form submissions, or an overall default owner so all contacts have an owner by default?

I see I can set an email to the Contact Owner but cannot see how to set a contact owner. I tried a hidden field named owner but that seemed to be ignored.

Thanks.

This may not be an ideal solution but we created a MySQL trigger that switches a lead from blank to a certain user ID and that seems to work well for our needs at this time. This lets them be created with a default contact owner but can be updated later to none if needed for whatever reason. Here’s the trigger if anyone wants to try something similar:

DELIMITER $$
CREATE TRIGGER `default_owner` BEFORE INSERT ON `leads` 
    FOR EACH ROW BEGIN
	IF NEW.owner_id IS NULL THEN
		SET NEW.owner_id = 1;
	END IF;
    END;
$$
DELIMITER ;
