Add a 2nd Sort criteria function to the "Sort Paperwork" when despatching orders

When printing orders we have a options on how to "Sort Paperwork" We currently sort by SKU but would like to sort by Pickbin.

When sorting by Pickbin the orders are then sorted by Pickbin but in that paperwork the orders are then sorted by order number which puts them into arandom order with regards to SKUs within that pickbin.

It would be great if we could sort overall by Pickbin but then within that the orders are sorted by SKU
