One way to do it is simply fill in the blank space the same pale blue that C-C uses. Of course, the trick is matching the color (pause while I hit the preview button)...just a little off. I used R 200, G 215, B 252. If some kind soul knows the actual RGB values, let us know!
Ahhhh, the glory of editing your post. R 198, G 210, B 245. Closer, a touch too much red, but it's real close.
