Once upon a time, when editing a user's directory access rules, any and all inherited rules showed up as well (shaded, to distinguish them as inherited).
This allowed you an obvious location where you could view all access rights that a user has in a single place - and be able to distinguish between inherited and discrete rights.
It would appear that Serv-U no longer supports this, but being able to view all rights a user has in one place is a necessary and industry-standard feature. This functionality should be restored to Serv-U as soon as possible.
