New Barcoding Process

Hi

Yesterday I received an email about the new barcoding process. As part of it it said to review your current product list (the file on OneDrive I presume) and "Mark each product with YES (keep) or NO (remove)".

However there is no identifiable column for this. Since I'm not making any changes (I already have individual codes for each item), do I still have to do this and if so, do we create a new column to mark each line "YES"?
