DriveWorksXpress suppressing individual parts in a assembly

[Xmodgeek]

Hello, I've been working on using DriveWorksXpress to automate our process of model creation.
I'm having a problem with suppressing or unsuppressing individual instances of a part or sub-assembly.

My example would be I have a basic truck body platform and it has stirrup steps on the sides and I want to be able
to specif if it's on the right and/or left side or even no step.

So far I can suppress or unsuppress the file itself by changing the file name rule.

Typically I would put two copys of the step, one on each side and suppress or unsupress them individually as needed in the assembly.


Thanks
