1. A method for creating an assignment between at least a first object of a first object hierarchy and at least a second object of a second object hierarchy, wherein at least the second object hierarchy includes a plurality of objects that are sub-objects of a root object and at least one folder represented by a folder object that is the root object for the plurality of sub-objects, and wherein a first subset of the plurality of sub-objects can be assigned to the first object, and a second subset of the plurality of sub-objects cannot be assigned to the first object, the method comprising: simultaneously displaying the first object in the first object hierarchy and the folder object in the second object hierarchy; selecting the displayed first object; in response to the selection, displaying an indicator symbol for the folder object, the indicator symbol indicating that at least one of the plurality of sub-objects can be assigned to the first object; and selecting the folder object to automatically create an assignment between the first object and each of the plurality of sub-objects in the first subset without creating an assignment between the first object and any of the plurality of sub-objects in the second subset.
