Subpartition by range?

Question

Hello,
I created the following partitioned table, using Oracle 11g R2 interval partitioning:
CREATE TABLE ACCOUNTS_IMPORT (
SIGNING_ACCOUNT VARCHAR2(16 CHAR),
REPORT_MM DATE,
IMPORT_ID INTEGER -- this is a unique number incremented by 1 (1, 2, 3,....etc)
PARTITION BY RANGE (REPORT_MM)
INTERVAL( NUMTOYMINTERVAL(1,'MONTH'))
(PARTITION p_first VALUES LESS THAN ('01-JAN-2006'));
Works correctly; every time I insert data for a new month, Oracle automatically creates a new partition.
For example: for the month of July I add 3 batches of records identified by IMPORT_ID 11, 12 and 13 and they all go into the same partition. This is exactly what I want.
But I also want that any record batch identified by the unique IMPORT_ID to go into a new subpartition. How can I achieve that?
Because IMPORT_ID keeps incrementing I cannot create from the beginning the subpartitions using something like:
PARTITION BY RANGE (REPORT_MM) INTERVAL( NUMTOYMINTERVAL(1,'MONTH'))
SUBPARTITION BY RANGE(IMPORT_ID)
SUBPARTITION TEMPLATE(
SUBPARTITION sp_11 VALUES(11),
SUBPARTITION sp_12 VALUES(12) ,
SUBPARTITION sp_13 VALUES(13))
Would be possible to add subpartitions on the fly or maybe get Oracle to create them automatically?
Thanks,
M.R.
