Morning Tom,
Thanks a lot for the response and clarification!
Based on the information you’ve given, if i use the Concat function to add the SKU to the end of the title for each individual item it should eliminate any duplicates? The problem i think we will have is when re importing the CSV it will create duplicates on the site as all of the original listings will stay on the site with their original handles, there will just be 1 with the SKU in the handle and 1 without. Or when importing to shopify does it remove all items from the site that are not on the current CSV being imported?
Sorry for all of the questions and hopefully they make sense!
Cheers
