No, they can't --- the fees are different in neighboring municipalities. There isn't one single all-in rate they can charge everybody who walks in the door, which is the whole problem they're complaining about.
The ISPs are asking, explicitly, to be allowed to quote a "maximum possible" price inclusive all fees, non-itemized, like you suggest.
