Fire and advance enabled by default?

[Danylo]

Is it possible to make Fire and advance enabled by default, like Fire at will, so the AI won't ignore it? I really need to make this mechanic work in my mod, tried to edit unit_abilities, but it doesn't work.

If you're editing a mod, edit the tech for fire and advance first into 0 instead of 4 so its enabled from the get go.

I know about that, but it's not what i want. I want to make fire and advance enable in battle without clicking on it, like fire at will, for example. My goal is to make AI use fire and advance.
