Training transfer points need to be added so players can use multiple players

@mendozzamagic but that's not the issue, imagine the situation of a card in training 30, if it is placed on the market it will give a warning "read carefully" that the training will be reset, in order to sell a card then the only more or less certain option would be to train another card to win the training and waste the coins of the player who had trained.
Because the game currently encourages us to stick with just one team for the entire season, this needs to change
