Department Setup?

Department Setup?

Hi,
  1. Is it possible to set up company departments in Zoho Invoice?
  2. If so, is it possible to add users to specific departments?
  3. Is it possible to restrict users to their department dashboard, invoices, and timesheets?
If it's not possible, what is the best way to set up Zoho Invoice for a company that has several departments and needs to have an admin with dashboard, invoices, timesheet access to all and department managers who only need access to their department?
