No option to exclude "NULL" columns when insert statements are generated. (4258220)

No option to exclude "NULL" columns when insert statements are generated.

In SQL Navigator, there is no option to generate insert statements with an option to exclude "NULL" columns.

Eg: A Table scenario

Empno Ename SAL Comm
101 Andrew 2000
102 Bruce 2001 10
103 David 2002
104 Keith 2003 20

In Toad go to Schema Browser, Select A Table and on RHS Data Tab right-click and choose Create Insert for all rows, then check exclude Null Columns.

The output of insert statements is as follows:
INSERT INTO E1 ( EMPNO, ENAME, SAL ) VALUES ( 1, 'Andrew', 2000);
INSERT INTO E1 ( EMPNO, ENAME, SAL, COMM ) VALUES ( 2, 'Bruce', 2001, 10);
INSERT INTO E1 ( EMPNO, ENAME, SAL ) VALUES ( 3, 'David', 2002);
INSERT INTO E1 ( EMPNO, ENAME, SAL, COMM ) VALUES ( 4, 'Keith', 2003, 20);
COMMIT;

In SQL Navigator | Insert statments can be generated using the export option but how can we exclude null columns.
INSERT INTO &&table_name (EMPNO,ENAME,SAL,COMM)VALUES (1,'Andrew',2000,NULL)
INSERT INTO &&table_name (EMPNO,ENAME,SAL,COMM) VALUES (2,'Bruce',2001,10)
INSERT INTO &&table_name (EMPNO,ENAME,SAL,COMM) VALUES (3,'David',2002,NULL)
INSERT INTO &&table_name (EMPNO,ENAME,SAL,COMM) VALUES (4,'Keith',2003,20)
