Is there a way to change the default avatar in Kaddressbook? The current one is an awful green cartoon face drawn by a small child (apologies to the artist if you are not as I have described). As I only have pictures of a few family members and friends, I see it on 90% of my contacts. I would prefer a blank grey square as a placeholder.
