Clash Suppression of AECOsim objects

I am trying to write a Suppression Rule.  I need the rule to suppress the clashes between two different types of Catalog Types AND two different Catalog Instances.

So...

I just can't say "Don't Clash Beams and Wall Leafs" (Catalog Type versus Catalog Type)

I need to say "Don't Clash Beam | Steel Beam versus Wall | <insert Wall Type Here>)  which is Catalog Instance versus Catalog Instance.  Also, all Catalog Types of each type go on the same Level per standards, so I can't change the level of the assigned part.

My closes rule is the first rule that is a regular expression of an element in a file with a logical name...but that doesn't seem to be working....

What I really want is to clash Part versus Part like I used to in Enterprise Navigator

IF (Class("TriForma_Group) and (Part == "name of one part"))  

AND

 (Class("TriForma_Group) and (Part == "name of another part"))

THEN $SUPRESS = TRUE

but I can't seem to get the right rule.

Any thoughts?
