SKULabs features the ability to control how line-items are sorted when picking orders on an order's details page.
Simply add one of the flag variables below to your Manual Store's pick list template:
SORT_BY_CUSTOMIZATION_METADATA: Sort by line-items customization metadata
SORT_BY_LISTING_NAME: Sort by the name of listings linked to line items.
If you need more granular sorting behavior, reach out to support in chat for help configuring a custom sort string.
