Users can now be assigned a "sub-organization" separate from their main affiliation, allowing you to manage memberships and areas of responsibility that span multiple organizations. This enables more accurate management of the organizations each user is responsible for or subject to approval from.
This can be configured from the user edit screen in the admin panel, and can also be viewed in the Skill Map user side panel and the Profile screen in the mobile app. When not set, the display varies by screen: it is hidden on the web side, and shown as "-" on the mobile side.
