gb... currently, I'm running CW2016 Pro. There is a way to group steel plates of same size and weight, like the old way back in CW2012.
Go to Steel>BOM>Setup...click Sort Order. In BOM Column Selected, this list needs to narrowed down to two. I use PART_NUMBER and STEEL_TYPE. I have my own version of Part numbers, of course.

When you run Steel Bill of material, do Run > CUT. Doing TOTAL.. you will still get N/A for quantity.

I hope this helps.
