Hello,
I must edit the CSV and add a new field before i can use the copy plugin?
No, don't edit the CSV file. Just add the product_s_desc field to the list of the Template fields. So for example your CSV file has 10 fields and the Template fields has 11 fields. CSVI will match the first 10 fields from your CSV to the fields in the Template fields and the last field will be imported as-is. You can add a default value here or fill it with the copy plugin etc.
The published field is often used like that as well. You can have as many extra fields as needed.
Kind regards,
RolandD
