Yes! You can export the fulfillment date at the line item level from the Shopify order with EZ Exporter.

Simply select the field listed below under the "Fields" section of the Data Settings to do so:

• line_items.last_successful_fulfillment.created_at (Lineitem Last Successful Fulfillment Date)

This field is also available in the Custom Filters so you can filter the data to only export those line items fulfilled at a certain date or date range.
