Three training sessions already today, but still being asked to do two more

So I did three training sessions already today, and after my latest match I get notified that I need to do 2 more.
5 training sessions in one day is too much.

There should be a way to stop training sessions having any impact on your teams preparedness for the next game.

Let us decide if we want to train, and when.
We are the manager, are we not?

Before every game of the day, it's the same message.
Don't bother about it. It doesn't affect at all the players performance.
Last season I played almost half of my games without doing that.
It's just a reminder to refresh your game bonus (and to promote the new training system - lol)
