[rt-users] selectowner right?

[d tbsky]

hi:
   i have a queue which has rights below for user-group:

   CreateTicket
   SeeQueue
   ShowTicket

   and there is admin-group which has all the rights for the queue.

   when user creates a ticket, he can use the "owner" drop down list
to see the admin-group users and assign owner. i don't want user-group
to do this. can i prevent them seeing the "owner" list (or only see
nobody in the list)? i hope user-group can only create ticket, not
assign the owner. can this be done?

   thanks for help!!

Regards,
