Am I missing something??
You can put this in the bug tracker as a feature request if you like.
Along with what Michael P suggested regarding the bug/feature request, you may also want to mention it at the thread below. Michael P is an active contributor to that thread. Zbigniew may be also able to incorporate this into some other things he is working on in the Gradebook. That is, if he has the time. It might end up as a "hack" for now and be placed into a future Moodle as a feature.
More gradebook discussion
It would be nice view to have and it would also help to keep the work load down. Would also be nice to be able to print these kind of things via a "printer-friendly" page and/or PDF format.
It would also be a nice feature to have in light of the future MyMoodle pages and centralized reporting of grades.
Please post the link to the bug/feature request that you file so folks can easily vote for it.
