Copied InfoObject, now how to setup hierarchy?

We created a copy of the Business Content InfoObject 0FUNCT_LOC in order to add attributes. The Texts and Attributes were created with no problems. However, when we go to add transfer rules for the hierarchy, the DataSource 0FUNCT_LOC_HIER is not one of the ones made available. How do we give our custom InfoObject the same hierarchy that the BCT one has?
