Where can I configure the starting army for a hero? Auto-translated

Does anyone know where the settings for the starting army of heroes are located? =)
I couldn't find it anywhere; all 60 new heroes I created were made by selecting a hero from the manual who has a standardized army (a few creatures from levels 1-3).


But now I need to create heroes for the Elementalist and Warriors of the Elements factions, and they need elementals in their starting army.

I think it's hidden somewhere in the game mechanics; I recommend checking UIGameRoot. If it were possible to control the starting army, that would be really cool – semi-specialized units for each creature.

Here are a couple of interesting observations: if you assign a hero to a neutral town, they will disappear from the map when the game starts. However, if you place an NCF (Neutral Creature File) there, the hero will have creatures of level 1-2 from the NCF. This suggests that there is an algorithm that fills the creature slots, and the quantity depends on their growth rate. However, heroes like Razaz or Laslo do not follow this algorithm due to their specializations. The specialization is tied to a specific ID, meaning it's linked to a SINGLE unit, and the bonuses will be applied to that unit and its upgrades (but upgrades of those upgrades will not receive any further bonuses).
