LEAP Bridge Concrete Superstructure

Is it possible to define a bridge with non-parallel abutments where every prestressed beam length is different? 

I have created a file with supports that have different skew angles, and the rendering looks correct, but when I do the analysis all the beam lengths are the same and all the self weight force effects are the same, and seemingly based on the span length measured along the alignment only. I have 15 beams to investigate, it would be nice to have them all in the same file instead of making 15 separate files!
