How to Import Sales Order header or line Attachments Using FBDI

Summary:

We have bulk sales orders that are getting imported using FBDI. Can attachments be added to an order or line when they are imported using FBDI ?

Content (please ensure you mask any confidential information):

Since we have huge volume of sales orders that are getting interfaced, we are using FBDI file import to upload such orders. Some of the information is supposed to be loaded into sale order line attachments of type text. We couldn't find way to have attachments added to Sales Order FBDI file. Is there any other FBDI or any other way to bulk upload such order line attachments?
