Scenario: An organization is broken down into a hierarchical structure of offices, departments, divisions, sections, and branches. Each unit has an Name, Acronym, human resources organizational code, information technology organizational code, and internal accounting codes.

(1) The SharePoint Online development team is routinely creating lists/libraries and content types across multiple collections and sites that prompt the users to select an organization and upon this selection bring in the organization's related information such as it's HR and IT codes.

(1) The SharePoint Online development team is routinely creating lists/libraries and content types across multiple collections and sites that prompt the users to navigate down the hierarchy. The user selects the office in one parent field and a second, child field populates with the departments to choose from. This repeats until the user reaches their desired level, e.g. if the user is specifying a division they stop once said division is selected. With this selection the organization's related information, such as HR organization code, are brought in.

Support for such a use case within a content type that could be published via the content type hub would be a HUGE time saver. When the organization/codes change the changes would only have to be made within the content type hub, cascading down throughout the tenant sites.
