Designing with AASHTO LFD criteria

I was wondering if there is a way to change the code PG Super uses from AASHTO LRFD to AASHTO LFD?

PGSuper has never directly

PGSuper has never directly supported LFD or any other specification than AASHTO LRFD. However, you can get pretty close to an LFD configuration by creating a Project Criteria library with custom trucks, load factors and allowable stresses. I don't recommend going this route though. You are better off using an old version of PSTRS13 or purchasing an LFD-specific program.

PGSuper was written by

PGSuper was written by WSDOT to support LRFD back in 1994. Because PGSuper is open source software, you have full access to the source code and you are free to add support for LFD.
If you are not sure how to work on the source code yourself, you can hire someone like BridgeSight to provide those services.
