Regarding partial problems, t's possible and even quite easy for a Problem Setter to write a judge that will show users a table with statuses for each test (like in MPOWER) or one that shows on which test user first got WA/TLE/RE, etc. (like in LCS).
As for the main request (regarding NZEC) it won't be changed/added, so I'm moving the thread to the archive of wishlist (wontfix).
