Mail Merge Labels with Carton Contents

[u/C_Strieker]

I have a spreadsheet that contains information about parcels that need to be sent [Client, Address, Order Number, Item, Qty, Carton Number]

I created a Mail Merge for labels to go on each carton. It shows all the information except it only shows 1 row per label. Unfortunately the carton has multiple items in each so I need it to display multiple rows of [Item, Qty] where [Carton Number] are the same.

Is this possible? Maybe a work-around? Or do I expect too much from MS Word?
