How to download current listings via CSV - including Search Terms and Bullet points etc - Amazon Handmade

Hi,

I'm trying to download my entire Amazon catalog of inventory as I would like to update the images across all of my listings.

So far I have downloaded 'Open listings' , 'Active Listings' and 'All listings (custom)' but none of these spreadsheets include the data entered into the Search Terms field or Bullet points fields??

FYI I have been manually adding products as I find it easier, however now I want to bulk update, I really don't want to manually add the new image to 100+ listings individually so I was hoping to download current listings and then 'Partial update' the inventory. Is this possible?

Thanks
