Hello I have the following question for usage of Odoo 8.

I create a Sales order with the following setup:

Shipping Policy: Deliver all products at once

Create Invoice: On Delivery Order

Under

Setting > Sales -> Generate invoices after and based on delivery orders is ticked

Setting > Warehouse -> Create and open the invoice when the user finish a delivery order is ticked

I confirm the sales order and go to the warehouse for packing. After packing I need to click on the button "Create Invoice" A wizard opens and I need to enter the invoice date and basically confirm a journal

How could I avoid this step. I would prefer that a Draft Invoice is created just after packing without pressing any "Create Invoice" button since this in total is very time consuming.

Thank you
