Editing the Project Invoice Line description in Bulk

Hi

We want to edit the Invoice line description for the Project Invoices (Created in Project Billing Module) in bulk through bulk upload for many Tasks at the same time. By default the Project and task details should be reflecting on the Invoice lines but there should be the flexibility of changing the Invoice line description in bulk through excel templates but we are not able to find any option to achieve this requirement. If there is any possibility to achieve this please let us know.

Thanks & Regards,
