Hello everyone,

 I have a question regarding the import of customer invoices in Odoo's Accounting module.  When I import invoices, each line is being treated as a separate invoice. I would like to know how to import invoices so that multiple lines (for the same invoice) are grouped together in a single invoice, rather than being split into multiple invoices.  Could someone guide me on how to structure the import to ensure that all lines for a particular invoice appear in one invoice, instead of multiple invoices being created?  

Thank you for your help!
