Доступно с лицензией Production Mapping.
Production Mapping provides several functions for working with multipart features.

If you have a multipart feature where you do not need all the parts any longer, you can remove parts by deleting them. This deletes the part of the feature entirely and updates the geometry attributes of the feature such as the length and area.
