There are a few different methods shown in the attachment tab of the ViewFlex toolkit. These methods are Cylindrical, Spherical, Solid Feature (e.g. face, edge) and closest nodes.
You should be able to make use of these methods to properly select your RBE2's slave nodes. If not, an FE pre-processor may be needed to proper define the RBE2 elements.
