This is a discussion from 2018: https://fifaforums.easports.com/en/discussion/413661/copy-from-balanced-tactics-in-seasons
I will just copy it here all over again because it's just surreal that the same problem still exists:
Is there a way in Seasons to copy the Balanced settings to the other 4 tactics sheets.
Seems crazy to have to set up 5 different layouts from scratch every time you want to try a different formation.
I think this is a feature in FUT, and I can't believe that it doesn't exist in Season.
Not sure whether this is a feature that might get added or if anybody has a workaround to make the copying of formations less painful.
We will soon have to pay again to keep playing on FIFA 21 and EA can't even copy the same functionality that already exists in another mode?
