How to Can we apply single credit note against multiple invoice with FDBI TemplateAutoInvoiceImpor?

Summary:

Need to apply using the FDBI template of autoinvoice from one credit memo to many invoice

Content (required):

Our specific context is we create integration between external system to AR transaction using FDBI template (AutoInvoiceImportTemplate) but in the external transaction apply one credit note to many invoice.

Now can run this process correctly one to one but need to one to many.

Our integration is divide in 2 process first the creation using FDBI and the second use a SOAP to apply the credit memo to the invoice.

We have issue in the first process that is because the data is coming in 2 lines with the same credit memo and them apply to different invoice but the autoinvoice start process detect error by duplicate, how can fix to prevent that duplicate line because that is not true.
