Complete orders and generate PDF

Good afternoon people, a query, it would be possible by code or in another way, select for example, 4 orders and in the Woocommerce selectable, that when you give PDF Invoice at the same time that it generates the new tab with the PDF those orders pass your been completed?

I think it explains well if they do not tell me that I try to explain it with screenshots.

Greetings and thanks in advance to all.
