How to buy multiple items at once at the AH?

In WotLK, I am using the Auctionator addon (ver 2.6.3) to buy multiple items at once when at Auction House (AH). I am using the "Buy" tab.
But Auctionator for TBC (ver 1.1.1) doesn't have such an option

Is there any addon capable to do that for the Burning Crusade WoW?

Thank you
