I know that this isn't a helpful suggestion, but when I hear this sort
of thing, my initial thought is: "it's time to get new auditors."
As many of the other people have pointed out, and as you suspect, this
sort of thing doesn't scale to the size that you're talking about, and
somewhere along the way, it will get in the way of research.
Your auditors ought to know this. If they're not taking your environment
into consideration when making recommendations, I question if they're
doing their job appropriately.
