You can correct this via a  
workflow that sends a curl script to the correct eBay API
I wanted to get started on automation, but haven't gotten around to it yet. Here's my current status.
There are 3 requirements:
1) ebay dev account to get auth token
2) External order number (ORDER ID)
3) Auth token (TOKEN) from 1)
This allows you to create the following script and receive all order data (including the billing address). Of course, this still needs to be filtered.

		curl -X GET "https://api.ebay.com/sell/fulfillment/v1/order/<ORDER-ID>" -H "Authorization: Bearer <TOKEN>" -H "Content-Type: application/json" -H "X-EBAY-C-MARKETPLACE-ID: EBAY_DE"
