Europa League and Conference League

Why the user can't play a friendly match or a league phase match of Europa League or Conference League? Why is it possible with Champions League and Libertadores only? KONAMI let the user play a match of europa league whenever he wanted.. now i can't play a Athletic Club - Roma or Manchester United - Real Sociedad without it being the final.. this is so stupid and I really don't get it. I suggest that in the next EA FC we should play league phase match in kick off of the other UEFA competitions, or a "friendly match" like there is for Conmebol Libertadores. I hope someone will read this
