Printing Individual Invoices when all Pending orders are highlighted and selected

[Seorch]

Hi,
When I select all pending orders to complete using one-click order completion, all the invoices are put into one pdf as the selected printer.
How do I get an individual invoice for each order and automate the invoice pdf name to the order number?
Thanks in advance.

Ah, this works up to a point now as it was an issue with v16 but now I'm on V18 it seems to work with the top most order processed first so i can manually add a file name when prompted.
It would be good to automate file names though if anyone has an idea how to do that.
