Yes, many of us would like this, Unfortunately, it would mean completely reworking the way the system actually operates - Terry explained it all in a response to a request several years ago. Essentially, the system only recognizes the correct answer, takes no notice of the incorrect ones.
Anyway, Terry knows we'd like this, and if he ever needs to rebuild the whole place from scratch, he'll put this in, I'm sure. Don't hold your breath, though.
