Créate a League, Cup, And Club permanently on your career save files
instead of create a club you could do create a league where you can make a league and have it be used in a career mode like the create a player where it’s always there
Adding the name of your created league have the country of this league add teams you make to these leagues and adding your own created players to any of these clubs
You can customize how many teams are in this league adding specific club ratings and custom placements
Example: You make a league for Bulgaria and make it so if you get 1st-3rd you qualify for Europa League
If this gets added you could also make a create a cup that stays through all your saves in career mode so it feels more authentic
This would help as to make the game feel more explorable and help the game be more popular from all these FC movies people make.
If you create a cup that stays through all your saves it would help make the game more authentic as to create a Bulgarian Cup, Super cup, etc.
