Add 'BillToAccount' field in Purchase order acknowledge outbound CMK

Summary:

After Sales order gets created with Order source as ORA_ELECTRONIC_DOCUMENTS, We are going to 'Under Validate Outbound Collaboration Messaging Setup' and selecting 'Purchase Order Acknowledgement - Outbound', the message payload it generates does not have 'BillToAccount' field, So, Is there any way with which we can get this field in the payload?
