Hi Experts

Can you please advise if the Cateogy field is selected within a Service Request, can an assignment rule be created whereby it will automatically assign the category to the correct queue without it defaulting to a default value and the client having to select this separately. eg. Sales - Additional Dueties going to Sales. HR Query going to the HR Queue
