There MAY be an option at the top of the 'sell your item' page to prefill info.
I don't have it any more as I kept unchecking it; it has now gone away.
Be aware that the Nielsen data is not always correct, and it is specific to ISBN, not particular editions. It also leaves you open to having fiction predetermined as textbooks, or children's books. Examples that I have seen.
I also saw one where Nielsen had the incorrect author name. I think I was one of only two sellers listing with the correct author.
