Is there a way to upload AP Invoice Distribution DFF through FBDI?

In AP Invoice Upload FBDI Lines page, we have Distribution Set and combination available. But how can we pass Distribution DFFs in that sheet? All the attributes in AP_Invoice_Lines_Interface seems to be for AP invoice line. 

Our requirement is to copy the AP DFFs to Projects. Now only DFF which can be copied to Projects is AP Distribution DFF, not line DFFs. Therefore, when uploading an invoice, we need to populate those fields. But we don't see the distribution DFF fields available anywhere in the FBDI.
