Yes… sorry, @robertgranholm, but it is a garbage-in/garbage-out problem. Unfortunately a lot of the large data-driven companies that we all work in our daily lives with have gotten pretty protective of their immense data sets. In particular, I think they worry that sending robust CSV reports to customers via email gives rival Google an edge in data harvesting through the ubiquitous Gmail.
Rather than offer clean & comprehensive reporting in formats that are useful to their customers, the tech titans now tend to minimize, obfuscate or not offer any reporting at all. (Apple Cash is a example of the third group… how hard would it be to export a report on cash transactions for Apple? so why am I left transcribing the numbers off a tiny screen? 
)
Anyhow, as @jpfieber said, the Line Item Import workflow does its best with the data we have access to. There are some screen-scraping Chrome add-on projects that may provide more comprehensive data but they don’t appear to be in compliance with Amazon ToS and are pretty brittle when Amazon changes is its site in trivial ways.
