Hi all, we are new to Shopify but we had a store on Ecwid. I mainly have apparel items on our store that we make and sell. I used Cart2Cart app to move all my products over but they said because of a limit they put how many variations can be transferred most of my apparel listings now only show sizes Small- Large. I need to add sizes XL-3X to most of these. I looked into using the bulk editor, but it does not give that as a variation I can change. Does anyone know how to do this. I have almost 90 apparel items and do not want to edit each one.
