Multiple Employment

Asking on behalf of a customer: 

"We are wanting to work with the multiple employment in order to allocate costs more definitively within our head office departments i.e between property, marketing.  We currently have one cost centre for our head office. Is there a way of being able to allocated labour costs to these different departments (multiple employment) without incurring additional costs by setting up a new cost centre, assuming that a new cost centre will incur additional costs."
