Second division

[Vitalton]

Hi. I would like to know: does anyone know how to create a full second league for any real league? For example, for the Polish league, to create a second Polish league and implement the promotion of the worst/best teams between them, and the participation of teams from the second league in the country's cup. I have done some mods before (I completely remade an existing league for my country's league - names, colors, kits, logos, etc.), so I know a little about modding, but I know that new files cannot be added to the game, and I don't know how to link the ID of some other logo (for example, a team or a FUT tournament) to a custom league or team. I play only career modes, and online, league, cup, etc. do not interest me.

Or is it possible to combine the two leagues into a full-fledged divisional system? For example, Polish and Romanian, so that they would be the Premier League and Second Division of one country, a common cup and promotion/relegation
