[otrs] New Ticket option !

Hi all!!!!! Im trying to make a script that can block tickets to users, so they dont have to choose the tickets from the main page. The problem is that I need them to be seen as "new ticket" and not only be the ticket blocked to a user. ( so the user knows that has a ticket to view ). Anyone knows how to modify the "new ticket" option????? Thanx in advance!!!!!!!!!!! ---------------------------------------------------------------------
