Negative Auto-Fill Values

[ForTheSwarm]

Is it possible to have the editor auto-fill negative real values? I know shift-clicking works for 1 value, but not for auto-fill. If not, is there a third-party editor which would allow me to do this?

If possible; you should be using DataID's to help you out. They're capable of reading negative stat gains; at least in my experience.
DataID's are things like <A001,DataA1,%>%; which, in-game will turn into things like this: Endurance aura increases all nearby allied units movement speed by 30%.

Of course; you cannot do this with triggered spells though, unfortunately (Unless it's triggered in the sense you're creating dummy units to cast other spells for you)

I would fill the values as positive first and then go over each manually to add the minus. It's tedious, but possibly a bit less.
