The eInvoicing users can 'duplicate' an eInvoice, which will create a brand new eInvoice, pre-populating it with the data from the last invoice. This duplicate invoice can be changed to update the details of the latest one.

 

 

 

This can be done by going to the invoice listing screen, hovering over the actions icon next to the invoice that you want to duplicate, and then hitting on 'duplicate'.
