Ticket Recurrence

Hi guys,
I have set many recurrence tickets. But whenever these tickets are created as per the schedule, it gets assigned to the owner (creator of the recurrence tickets).
Now, many a times, the owners of the ticket are not available and no one gets to work on it.
I want to know if there is any way to change the owner to unassigned from the beginning?
Can workaround the code as well.
