Is there a way within TPP to change the way the heading within the tab (not the ones across the top) display? Currently, it's using '<h2 class="centerBoxHeading"> I don't want that kind of header in this location.

I think I can get it done going into each template (xsell, also purchased, etc) but I'd like a more centralized approach. Can I add something in one of the tpp stylesheets?
