I-Beam Flatcars

This may be a picky question, but the LV Flatcars when loaded, show just one load of I-Beams.
The IIR Route the forklift driver loads two rows of I-Beams.
Is it possible to change the flatcars to two rows of I-Beams, IIR to one row of I-Beams, or where could I get I-Beam flatcars that have two rows when loaded?
Thanks

Notice how the preloaded car (in front of the empty) has just one stack of I-Beams.
