There should be a way to export the file with SKUs in each cell of the first column and their Variation SKUs in the corresponding column like the way we import them into linnworks.
Right now with Variation Items by Parent all the SKUs appear in single Cell with a separation of comma. They should be vice versa. i.e. SKUs in each cell and Variation SKU in the next cell with separation of comma (if the SKU is in multiple Variations)
