adding to the quick combat enemy pool

Hi All,
New to CFS2, I've been installing some addon fighters to CFS2, and noticed they don't get automatically added to the list of quick combat enemy planes one can choose to fight against. So unlike in CFS1, I can fly my addons but not fight against them. Is there a fix for this or is it just not possible to do in CFS2?
Thanks in advance for any info,
