MMH5.5 - Heroes of Might and Magic 5.5

Thank you very much!!)), one more question: how can I replace a creature within a faction with a custom one, instead of the standard creature? I want to replace the NCF creature, for example, this archer: https://psatkha.narod.ru/creature_433.html, with a 2nd or 3rd tier creature from the Elves. Does version 5.5 support NCF creatures?
