ATOM IDE; how do I format conditional defines?

Hello,

I recently switched from Eclipse to Atom (in conjuction with platformio) and I do like the setup a lot. But one thing I have not been able to achieve just yet (could not find any directions) is to format conditional defines in the code so that they show up for instance as “disabled” code (different colour or background colour) when a define has not been set. I am programming using .cpp files with the atom-beautify package active.

kind regards
