How to do Bulk Invoice grouping by PO?

Hi There

I am trying to do the following:

I have multiple invoices for a single customer in any given period.

The invoices are created from an integration with another system.

I am trying to group the invoices together in consolidated invoices.

The invoices are consolidated on the basis of those with the same purchase order and for a given invoice date range.

This works correctly when I do that using the following screen

However, I was wanting a way to do this in bulk. i.e. generate invoices as at a certain date and consolidated by purchase order for all customers
