The Client identifies that a segment of customers need to see some products on the site that other customers should not be able to access. All products are maintained within one catalog but in separate categories. A custom attribute will be used on the Profile system object to identify customers that belong to this special segment. A customer group will be made that is qualified for by this Profile custom attribute. The storefront will be customized to include navigation to relevant categories for this customer group. Unfortunately during technical review the Client points out that the business teams have raised a concern with maintenance and want to use a shared navigation within the catalog and not use separate categories. Which item should the Architect suggest to efficiently fulfil this new requirement while maintaining scalability?
