Susan, if you mean the list of brushes, yes a property set would be perfect.
Create the property set on the SyntaxHightlighter Create/Edit snippet page, call it articles and just add the one property: brushes with the comma-separated list of brushes.
You'll still need to specify the brush you want for each section in the pre tags.
