For the moment, you can assign value to item in when-new-record-instance by checking system.mode (insert mode), increment it for every new record.
By using sequence:
you can make use of sequence (sql object).
Assign <sequence>.nextval to display item in pre-insert trigger.
not sure, you may need to use 'synchronize'.

PROCEDURE seqno_prc(p_sourceblock IN VARCHAR2, p_sourcefield IN VARCHAR2) IS
v_currec NUMBER(4);
v_curfld VARCHAR2(50);
BEGIN
v_currec := :SYSTEM.CURSOR_RECORD;
v_curfld := :SYSTEM.CURSOR_FIELD;
LOOP
COPY(:SYSTEM.CURSOR_RECORD, p_sourceblock || '.' || p_sourcefield);
IF :SYSTEM.LAST_RECORD = 'TRUE' THEN
EXIT;
END IF;
NEXT_RECORD;
END LOOP;
GO_RECORD(v_currec);
GO_FIELD(v_curfld);
END;
-----------------------
WHEN-NEW-RECORD-INSTANCE
BEGIN
If :SYSTEM.RECORD_STATUS in('NEW') THEN
--seqno_prc('block_name','item_name');
seqno_prc('dept','deptno');
END IF;
END;
