例如，我一次性在购物车加了很多款游戏，但是我想选择某一些进行购买，但是没有这个功能，导致我只能删掉我暂时不想买或者有分批购买的打算的游戏。
For example, I add a lot of games to my cart at once, but I want to select certain ones to buy, but I don't have this feature, so I have to delete the games that I don't want to buy for the time being or that I plan to buy in batches.
