A system is described that includes a host computer and a user interface module executing on a client computer. The host computer maintains data for shipment items, and the client computer executes a user interface module that presents a user interface that includes at least one activity region having a preference control input and a set of data fields to display at least a portion of the data associated with the shipment items. In response to activation of the preference control input by a user, the user interface module presents a preference control window to selectively enable and disable the inclusion of each of the data fields within the activity region.
