BRCM - BOM catalog Number Error

I have placed:

(System) "Cable Ladder"

(Catalog) "Cooper Cable Ladder Series 2,3,4 * 5 Aluminum"

(Variant) "Width 12" Height 6"

When I run the BOM while the description is correct (e.g. 12" width 6" height) the catalog number is for series 24, the lightest cable tray.  We, as far as I can see, have no way to pick the series that we want, 24,36,46,H46, which each require different support distance due to cable weights.

We did not notice this on one job and got into trouble with support requirements.

My question is exactly where is it that we can lookup and modify these catalog numbers so that we can use the series 36 numbers always?

In fact I think what I would like to do is to model with the "Solid Bottom Steel" for looks and have it spit out the BOM for ladder tray.  This way we use the actual model to create the drawings in a much more friendly look, rather than ladder and not have to create another separate 2D raceway model that still needs to be modified to look correct.
