Debugging Logging Lines - Color Differentiation ?

Hi,

I wish to enhance some of our code to include diagnostic debugging logging lines. I Know I can do this by using a 'D' in column 7 and setting WITH DEBUGGING MODE against the SOURCE-COMPUTER. What I would like to know is is there an easy way to change the color scheme so the 'D' lines appear in a different color, they take the same color as a comment line which is not great as I'd like to differentiate them from comment lines.
Failing that is there something else I could use, put a different character in a different column perhaps to trigger a change in color scheme for these lines ?

Thanks in advance.
