Delete or Modify Default Teamlink Security Roles

Default Teamlink Security roles cannot be renamed or deleted? Users should be able to Delete, or if not, at least rename the default roles because they cannot be changed; Changes to default Teamlink Security roles cannot be saved. So if someone wants to change the Architect default security role, they cant save the changes, they can't rename it, and if they create a new security role for Architect #2, per se, whats to keep someone from accidentally selecting the unwanted default role?
