Another workaround, even more hacky, involves no code but 2 Zaps.
This would be via the particular Zapier action types that support line items, such as Google Sheets. The first step would be to use Zapier Formatter’s built in split function and in “Segment Index” choose all. Then, add a new row in Google Sheets using the option hidden under “less common options” : Create Spreadsheet Row(s) with line item support. Then, a 2nd Zap could trigger on the new row and take care of looking up the information needed.
