WP ALL IMPORT

I’m using WP ALL IMPORT to import a CSV file with all of my products. I have custom tabs that need to be created. In my case, lets say, care instructions. Now, in order to create and dave a tab, I have to fill it with content. However, each product has different care instructions. So, how can I put in content when I am creating the tab, when each product needs to have its on unique content underneath that specific tab?

Please help.
