well you can do it manually but it means that after every kill you have to paint another one on! Just load your skin into paint or photoshop (or any image editing program) and simply paint it on! Very easy to mark for Luftwaffe as its just a straight line on the tail. I did this once in a Russian campaign where I marked German crosses (not swastikas-more effort) on the side of my I-16.
