How do we add a line level DFF to the payables invoice adfdi?

Summary

We have a DFF at the line level that we need to be able to populate using the Create Invoice from Spreadsheet option in Payables/Invoices.

We have a DFF deployed at the payables invoice line level.  The DFF appears in the Details area of the line information.

We are able to import data into this field using the FBDI, but we are not able to find the field on the adfdi when attempting to create an invoice from a spreadsheet. 

Are there additional steps that need to be taken to add this DFF to the spreadsheet adfdi?  I have attached a screen shot of how the DFF is set up.
