BeingFemale scripting advice (?)

[BookBurner]

So, I was thinking about fixing actor spawning in being female mod, which is already prepared to spawn child actors, but does not work properly if more than one actor is spawned (because of same actorbase value of child actor). I was tweaking the original script and I got stuck on FWsystem script, to which I can't add a new property. (empty formlist, to which I will log every child actor spawned with birth, so actorbase will be used only once per child type). Is there a way to add script property by any other means than CK?

Soooo no way to add properties to script without CK I take it?
