Need an addon to make bid price match buyout price

[a95kN5uF4348SC6]

Is there an addon that makes the bid price match the buyout price? At the moment I'm using auctioneer and it doesn't do that. Just a minor annoyance when its 5-10 listing but when you are doing 20+ it gets really irritating.

Preferable something that works along side auctioneer. If not I'm willing to ditch auctioneer entirely if it at least scans the listed item for the lowest buyout price so that I can undercut.

I clicked Icecrown > addon subforum but it took me to lordaeron > addon subforum so sorry about the double post if anyone was wondering.
