Run custom event in specific queue

Hello,

I have a custom event that is triggered when new transport task is created.
This event is run in background because when not I receive an error because I want to change a record that is still locked.
This works fine. Only when there are a lot of background jobs there is a delay and that cause problems.
To avoid those problems I want to place the background in a specifiek queue so it is executed straight away.
See below my current code.

Those any one has a solution for that?

DECLARE
   attr_                VARCHAR2(32000);
   sql_msg_             VARCHAR2(32000);
   stmt_                VARCHAR2(32000);
BEGIN
      stmt_ :=
      'DECLARE
          info_ VARCHAR2(32000);
          objid1__ VARCHAR2(2000);
          objversion2__  varchar2(300);
          attr_ VARCHAR2(32000);
          row_key_   VARCHAR2(32000):=''&NEW:ROWKEY'';
          transport_task_   VARCHAR2(32000):=''&NEW:TRANSPORT_TASK_ID'';
         CURSOR get_objid IS
           SELECT OBJID, OBJVERSION
           from ifsapp.TRANSPORT_TASK
           WHERE ifsapp.TRANSPORT_TASK.OBJKEY =row_key_;
           
       BEGIN     
        FOR REC_ IN get_objid LOOP
            objid1__  := REC_.OBJID;
            objversion2__  := REC_.OBJVERSION ;
            Client_SYS.clear_attr(attr_);
            Client_SYS.add_to_attr(''FIXED_DB'',''TRUE'', attr_);
            ifsapp.TRANSPORT_TASK_API.Modify__(info_, objid1__, objversion2__, attr_, ''DO'');
            COMMIT;
        END LOOP;
       END;';

      sql_msg_ := Message_SYS.Construct('RELEASE');
      Message_SYS.Add_Attribute(sql_msg_, 'SQL', stmt_);

      Client_SYS.Clear_Attr(attr_);
      Client_SYS.Add_To_Attr('SQL_DATA_', sql_msg_, attr_);
      Client_SYS.Add_To_Attr('MSG_', '', attr_);

      Transaction_SYS.Deferred_Call('Fnd_Event_Action_API.Action_Executeonlinesql', 'PARAMETER', attr_,
      Language_SYS.Translate_Constant('Event', 'UPDREV: Transport task Fix' ));
