There is no other conclusion, based on what you've just said. Perhaps the folks you deal with at each of these banks would provide something in writing stating that they are allowing you to run 5967 transactions legitmately, without coding them as such? If it were on each bank's company letterhead, I'd be the first person to refer you business.
