Tax Book Upload Interface

I have a large number of assets (6000+) that need to have the YTD and Accumulated depreciation figures adjusting. I have looked in the R12 FA user manual and seen the script for loading in to the Tax Book Upload Interface. However this script only appears to adjust one asset at a time. I'm not an SQL user so I was hoping that someone in the community could suggest ways by which I could easily and quickly get these changes uploaded into the tax book. As a minimum i wondered if it was possible to make the script

insert into fa_tax_interface
