Any way to identify which disk failed verify with Nero multi-disk burn?



I burn 3 disks at once with Nero (using 3 recorders) when making the training DVD’s that I sell. Occasionally I’ll get a verify error. When this happens I have to toss out all three DVD’s because I don’t know how to identify which DVD failed the verification. Is there any way to tell which DVD failed or a way to re-verify burned DVD’s individually against a Nero compilation?
