use batch execution for PreparedStatement

Hi,
 
I must insert many rows(e.g. 2.000-5.000) in a table. If I do this with save funktion from torque it is not perfomant. Also it doesn`t work with a subselect, because the data comes from a other database. Now I had the idea to do this with the BatchExcution of PreparedStatement. Can I do this with torque?
 
Thanks for your help.
Andre
