Heya Fervor ^_^

Thanks for the suggestion! It sounds pretty cool. I'll make sure to report it to the devs.
Actually there is a similar option in the game right now.
When you click on the training menu, on the bottom right there is a "Reports" button, and when you click it, you can see the last few drill combinations you did with your team and if you wish to, you can repeat them. But they aren't permanent and the oldest ones are not visible.
