Working with Group Manager
If there are certain sets of users who are regularly assigned to perform tasks for content items, you can make the assignment process easier by creating groups. An owner can then assign a group of people all at once by selecting a group name rather than having to select each user name individually. Keep in mind the following when working with Group Manager in User Setup:
Important: A group must contain at least one user and can consist of users from a single site or multiple sites.
You can create a group containing a single user to create a selectable title or role. For example, if there is only one person designated as the approver within a department, you could create a group called Approver that contains that one user. You can also use a single-user group in the case where one user sets a document/assessment as approved on behalf of an approval committee, such as a board of directors.
