Where did all the corporate identity stuff go?

I am missing all the designs for invoices, letterheads etc. This used to be in its own category but I am not seeing it anymore?

It’s here under Stationery.

I just see this: https://graphicriver.net/print-templates/stationery/proposals-invoices

and then I have to weed through dozens of things I am not looking for :-\

What exactly are you looking for?
