Universal Containers is a fast-growing company that sells containers globally. It has thousands of dealerships throughout the world where local dealers service Containers sold locally. They recently opened two dealerships in California: NorthCal and SoCal. Universal Containers implemented a new partner community to enable their dealers. Each dealership has a dealer Manager who has all service agents report into them. Assuming a private sharing model, what is the best option to enable dealer managers to have visibility to customer cases within their dealership and not across all dealerships?
