Mass bid with rating

You can find this feature from the transfer market.

After clicking the button in the transfer market, a panel will open with some options for you to choose.

Here you can choose if you would like to Buy Now or Bid, which rating you would like to buy, number of bids you want to place, and what price you are willing to pay. There is also an option to skip owned players meaning any player already in your club will not be bought.

Once you click start, the process will begin and you can see its progress in the panel.
