New UEFA format on season 1 with Data Update?

Is there any way to have the new UEFA format on the first year using the Data Update?

Currently it looks highly unlikely the game will allow it, sadly.

Did SI break the in-game editor or is it hardcoded to not be able to make any changes to the European formats?

The game just doesn’t like tweaks to it, even using the data that will come in a year into the game, Europe for some reason is always a problem each year, hopefully UEFA stop changing it so next year on its more stable to work with!
