It would be nice if we could set coach preferenced players at the training field. Correct me if I am wrong, but currently coach prefers players with lower shirt numbers and coach can help only 5/6 players in training.
Since people use numbers for different purposes, it would be inconvenient to revamp the for the training setup.
Teams that are competing in youth leagues have a lot of players and it is quite easy to use up most numbers in allowed range 1-99, leaving only narrow spaces for organization, which leads to necessity of shuffling and scrolling player numbers.
I have an ever increasing number of players that have reached their potentials in desired skills and I would like them not to sit around, but to continue training less important skills, yet having coach focused on other players for which those skills are more important.
In other words, coach preference should be selectable by other means, not only by shirt numbers.
