Is there any way to use the same name?

[Maksimkines79]

I don’t want to add a number to the name every time, is there a better way to do it?

It was much simpler

You can do it like

[SerializeField] private SpellConfig _config;
public SpellConfig Config
{
    get
    {
        return _config;
    }
    set
    {
        _config = value;
    }
}
