Google Maps Api v3: How to change the Default wayp

How do you change the markers with custom markers active in the map in the directions panel and change the color aswell from the body? Any help much appreciated.

Just to keep alive @MrUpsidown comment and code alive:

Short answer: you can't. Longer answer: don't use the directions panel. Create your own, with the information you need (from the directions service response) and add your custom markers.
