Pollyanna

While playing Pillars of Eternity, I see an icon of a head with some gears in it. If I right-click on that icon, I get a window titled "AI Behavior". In that window, there is a drop-down box that lets me choose from several options which affect how my character will behave during a battle. Is there any way to customize those options? I would very much like to write my own script to determine my character's actions.
