How do I make a hero available on all maps? Auto-translated

Please advise. I read how to create a custom hero; in the map editor, I placed a hero, replaced the model and animation in the shared folder, changed the hero's name, description, and initial spells. The hero was created, but he is only available on the map where he was made. Is it possible to make him selectable at the beginning of the game on a single-player/multiplayer map (on one computer), where you choose the castle, hero, and starting bonus? :confused::(
