TOC Macro hide headers by class

[Laker Sparks]

On my page I use the Questions List Macro which creates content with H2 and H3 headers. I would like to include H2 and H3 headers in my TOC, but I don't want the ones from the Questions macro to show up. I noticed that these inserted headers have a class. Is there a way to exclude headers not by a regular expression but by class? Or is there another approach that I'm not thinking of?

Can you exclude them from the TOC using the exclude field?
