Current questions and answers regarding the map editor.

A very important question about Heroes 5, the map editor. I am creating a map. In the Heroes scenario, there is Railag, who has the ability "Terrifying" - the higher the hero's level, the more the initiative of enemy units decreases, 1% for each hero level. But I want to add Railag with the ability "Master of Initiative" in the editor - for each hero level, the initiative of enemy units decreases by 1%, and for each hero level, the initiative of units under the hero's command increases by 1%, so for each hero level, the initiative of your own units increases by 1%, and the initiative of the enemy decreases by 1%. But there is no Railag with that ability. Only with the "Terrifying" ability. Is it possible to change his ability in the editor or add this Railag with the "Master of Initiative" ability? Or how can I make him appear there?
