Changing phisycal attribute for a sub partition

Question

Hi
oracle version : 10.2.0.4 on Solaris
I have a table with subpartitions and I need to reduce the initial extent of the subpartition without dropping and recreating .
I can do that on a table level and on a partition level using :
alter table xxx move storage (initial 65k);
alter table XXX move partition YYY storage (initial 65k);
But I cannot do a similar thing for subpartition
alter table xxx move subpartition yyy storage (initial 65k);
ORA-14160: this physical attribute may not be specified for a table subpartition
Any way to accpmplish this without dropping and recreating the table ?
This is needed as part of a huge data structure copy .
I get the structure from a production DB and I am importing them ( using datapump ) to development.
I need to "shrink" the tables because the initial extents defined are big and there are so many of them that the copied schema, thoufght empty of data is taking many GB of space.
I managed to "shrink " everything , only subpartitioned tables are still occupying a lot of space
Any advise ?
Thanks

Some more info :
I am using LMT in both production and test
but when I export and import ( datapump ) - the initial extents are not 'adjusting' themselves to the new tablespace in test.
So the original tablespace in production have a 100MG initial and next extent and the target tablespace to which I remap during the import has 65k initial/next extent - but nevertheless - the tables are getting created with the old extent sizes of 100MG.
The only way I found to fix this is to actually run alter table commands on the empty tables after import, and that works fine for everything other then subpartitions.
