2. Can you set up a defaulting rule to apply only for a specific operating unit and not globally?
Yes, this is possible. The default condition ALWAYS is a global condition and rules setup with this condition will apply to all operating units.

However, users can setup defaulting conditions based on the operating unit. These defaulting conditions can be set up for a combination of operating units or separate conditions can be defined for multiple operating units. They can then be used to setup defaulting rules specific to the operating unit.
