If necessary, you can also specify these qualifiers for each individual reference, in which case they would override any top level qualifier setting. 如果需要,您还可以为每个引用指定这些限定符,在这种情况下它们将重写任何顶级限定符设置。
I think that it's important because in case of a top of the table clash it is better to play the first game away and play the qualifier at home. 我想,这很重要,因为以小组头名出线后,在淘汰赛中,将会先打客场比赛,然后再主场,这样比较好。
