Hi Marco.
Thanks for reaching out today.
If they are required fields then you must provide values for them or else the entire feed will fail which will stop WP-Lister from being able to update the listings on Amazon.
If they are not required fields, you could download your own feed custom feed templates from Amazon which allows you to edit them how you please. You can download entire feed templates or just the basic fields when creating a feed on Amazon that can then be uploaded to WP-Lister.
To do this, you can click the “Add products via upload” menu option in the “inventory” section of your Amazon account in the top menu then go through step 1 and 2 and then click “Generate template” button to create your own custom feed templates which you can download and upload to WP-Lister (in the right hand sidebar of the “Categories” setting page of WP-Lister) to use. Then browse to the listing profile and select the new feed template you uploaded in the “Feed template” drop down selector.
Keep in mind, when creating the custom feed template you need to only select 1 marketplace during the feed template creation, WP-Lister does not support using multi marketplace feed templates (but you can list to multiple marketplaces with WP-Lister, just not with multi marketplace feed templates).
Then once you have downloaded the feed template you generated you could modify it even further by adding or removing fields before uploading it to WP-Lister.
You can open up the XLSM file from Amazon that you download and navigate to the template sheet then add a new column like from the image below:

In order to change the Amazon template file, you first have to “Un-protect the sheet” in your spreadsheet application.
Kind regards,
John
