The ContactItem object supports only a single built-in Categories collection. You could create other custom keywords fields, but they would not have all the same functionality as Categories. What you might do is have two unbound multi-select list boxes, one with corporate categories and one with departmental categories, and in the Item_Save event, merge the selections into a single list and use that to set the Categories property value. Note that this won't prevent users from right-clicking an item and changing its categories, although you may be able to work around that with additional code behind the form.
