How do you set the transaction commit level in SAP HANA?

I am using an odbc connection to send create table and insert statements to SAP HANA from IBM Cognos TM1 TurboIntegrator.  The issue I'm facing is that the process consists of many, many insert statements and it seems to be committing one at a time.  So it takes about 3 hours to load 3.5 million rows of data to one column table.  Is there a command to turn autocommit off from the odbc layer?  Or is there a better way to set the transaction commit size?

Thanks!
