erwin WP/DG harvesting and configuration updating

Can an existing configuration that includes an erwin mart library that was harvested be updated automatically if a new model name (not version) is added to the erwin mart library that was harvested?  I can schedule recurrences of the data model harvesting process that includes new models in the erwin mart library, but i haven't figured if you can automatically republish the same configuration if the contents of the erwin model library changes.
