FORALL with Multi-level VARRAYs

Question

Hello all,
I was wondering if the FORALL statement supports something like this:
FORALL i in 1 .. nt1.LAST
INSERT INTO t1 VALUES (nt1(i)(i), nt1(i)(i+1));
where nt1 is a multi-level varray defined as:
TYPE t1 IS VARRAY(10) OF VARCHAR2(32767);
TYPE nt1 IS VARRAY(3) OF t1;
Any help would be greatly appreciated as I don't want to put the insert statement into a regular for loop. Thanks.

Is it acceptable approach ?
SQL> create TYPE t1 IS VARRAY(10) OF VARCHAR2(32);
  2  /
&nbsp
Type created.
&nbsp
SQL> create TYPE nt1 IS VARRAY(3) OF t1;
  2  /
&nbsp
Type created.
&nbsp
SQL> create table tab2col (col1 varchar2(3), col2 varchar2(3));
&nbsp
Table created.

SQL> declare
  2   a nt1 := nt1(t1('a','b','c'), t1('7','8','9','10','11'), t1('a1','a2','a3','a4','a5'));

  4   type m1 is table of varchar2(32);
  5 
  6   c1 m1 := m1();
  7   c2 m1 := m1();
  8 
  9  begin
10 
11   c1.extend(a.count);
12   c2.extend(a.count);
13 
14   for i in a.first..a.last loop
15    c1(i) := a(i)(i);
16    c2(i) := a(i)(i+1);
17   end loop;
18 
19   forall i in a.first..a.last
20     insert into tab2col (col1,col2)
21     values(c1(i),c2(i));
