Current questions and answers regarding the map editor.

A very important question regarding Heroes 5 and the map editor. I'm creating a map. In the game's scenario, there's Railag, who has the ability "Terrifying" - the higher the hero's level, the more the initiative of enemy units is reduced, by 1% for each hero level. But I want to add Railag to the editor with the ability "Master of Initiative" - for each hero level, the initiative of enemy units is reduced by 1%, and for each hero level, the initiative of units under the hero's command increases by 1%, thus increasing the initiative of his own units by 1% and decreasing the initiative of the enemy's units by 1% for each hero level. But there isn't a Railag with that ability. Only with the "Terrifying" ability. Is there any way 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?
