Yes, admin users can create surveys for local departments. When building the survey, select from the Departments drop-down menu to right of each question to route the survey items to this group only:
What if my team is within one of these departments?
Use the people editor to create a new department and assign your team to it. Then you can assign the survey items to that new department.
Note: Macorva uses employees, not departments, as the structure of the org chart. Departments in Macorva are solely used for categorizing data. This means you are free to create new "departments" representing your teams, even if your teams formally reside within larger departments.
