is it possible to set a switch to prevent the auto assignment of all new  customers?   We have manually unassigned them on each existing customer which took ages - but dont want to have to keep turning this off as we add new one.   It was Especiallt tedious to turn them off for each customer as the luists automatically defaults to the beginning so you have to scrool back therough the list as you lose your place AND cannot search by assigned to bring them to the top of the list.
