Fiducal and Test Cupon

I was looking at a pcb from an product I was involved with some years ago. And I got to thinking how would I add such items as a fiducial or a test coupon. ICT points appear on the circuit diagram so its easy to create a library element for them. However fiducial and test coupons are pwb elements and don’t appear on a circuit. At least I have never seen them. Is a pwb only category for such items needed - in a similar way there is a schematic only category?
