Yes, but it would require some knowledge of scripting languages, such as Perl/etc. Most easily done on a Mac since Unix and all of that stuff is included.
You would need to use the XML converter to convert your 900 parts to (text) XML format, run your script to insert the new parameters, modify the 2D script and add the rotate prefix code to the 3D script, then run the converter to convert the XML to gsm.
