Not sure whether to post this here or in the FRED Discussions board. Since I didn't find a way to do it in FRED I decided to post it as a request. For SEXPS like ship-subsys-guardian-threshold it would really be helpful to have <all subsystems> as an options besides <all enginges> and <all turrets>. I often had the problem that the weapons subsystem of my hero wingmen got destroyed turning them to be absolutely useless. Just using ship-subsys-guardian-threshold on engines doesn't necessarily work out always either, as pofs have different subsystem names. The Bakha, for example, has two weapon systems.
