I have a MDR, and on the master there's a Roll up Field Summary on the details. If the # of the details > 0, I want to render a graphic for the user or highlight the field, or something. The Master's Page Layout is a STD page layout. A catch is that the decision will play off of the roll up field summary which is a little bit gimicky.

Can I do this natively? Otherwise I'll drop in a Visual Force and be done with it.
