Yes. This can be achieved from the “Service Desk Project Settings-> User/Role Management-> Roles-> Default User Addition Rule Button” page. In this page, do not select any User if you want to prevent the newly added Users in SapphireIMS being allocated to a Service Desk Role by default. For more information, please refer to the SapphireIMS Online Help Portal Link: Roles (Search for “Default User Addition Rule” in the Page).
