Regular Expression in Suppression Rule

Navigator SS5

I would like to know how to use a regular expression (or other technique) in a value.

Use case:  I have a rule that compares two different values in two different class elements.

The property in one value drives the comparison of the second value.

So what I'm really trying to do is this:    Suppress clashes if one of the clashing elements has CLASSOBJECT1.PROPERTY set to <Value> AND the other has the property CLASSOBJECT1.PROPERTY set to <same value> - String

Where in the above example... I have a class where a property value is set to 1000.  I want to clash another class where a different object is set to 1000-A1.    1000 is the variable...

Please and thank you.
