CONSPAN - Skew Angle

Hi, 

I am designing girders for a span that has no skew on one end and a 45 degree skew on the other. There are 7 girders with lengths that range from 102.5' to 142.5'. 

I used the center girder's length as the Precast Length under the geometry tab. Under the Diaphragm Load Wizard, the image shows the spans as they should be (with girders ranging in length from 102.5' to 142.5'). 

However, once I get to the Beam tab to design a strand pattern, I noticed that the program is using the center girder's length I input in the geometry tab for all girders. 

Is there a place where I can input the correct precast lengths for each girder? Or do I have to create a separate file for each girder in this case?

Thank you.
