Any Steem upvot bot that prevents overbidding?

Quick question - Is there any Steem upvot bot that prevents overbidding? Because this is what we really need right now. As far as I know every bots on Hive account@steembottracker allow over bidding, that means they can give you loss on your investment. Isn't there any bot dev who can build an upvote bot like this? I believe everyone will highly appreciate that.
