I always used to lay out pads across every recovery diode for a 10 ohm carbon resistor and a small ceramic tubular capacitor. If you pick a bad enough capacitor, you don't need the resistor. You can also use lossy ferrites. The key point here is that you do not want high Q parts for this application, you want them VERY lossy at the EMI frequencies. Others may have a different perspective on this topic.
