RFE for Datastage with DB2 BLU/MPP

Client use DB2 BLU for online inquiry and Data warehouse to improve performance of Parts Information System.
Their warehouse includes huge BLU table (table size is 30TB before compress) that is MPP configured.
Clinent uses Datastage to load the huge data into this BLU/MPP table. When client load whole new data into the table with replace mode using direct connections of DB2 Connector, the DataStage Job gets SQL27906N error.
SQL27906N The load operation was not performed because the specified parameters are not supported with the type of the target table.
This is because:
Parallel load function of DataStage put the OUTPUTDBPART_NUMS() option to each of the load command.
Performing replace load to a column organized table (BLU) gets implicitly the RESETDICTIONARY option of the load.
DB2 restricts to specify outputdbpart_nums() and resetdictionary at the same time ( SQL27906 )
Having the option to specify KEEPDICTIONARY option on the DataStage side can be a for this current restriction of DB2/BLU.As a result, client's load job takes so much time and do not finish during their batch window.
Our request to Datastage is that we can specify "Keepdictionary" in property of DB2 Connector to let Datastage produce DB2 load command with "Keepdictionary" .So Datastage parallel load replace job become possible with existing Dictionary.
