I use phpadsnew also. Very powerful tool
Don't know that it does that ponyman, but you do get stats showing ctr and can 'weight' a particular banner so it shows more than others, as well as a big bunch of other stuff that I haven't gotten into. It takes a little getting used to first off, took me a coupla days of real tearing hair out, but when you get the hang of it - wow!
