How do I hade a link to a genrated PDF

Hi

I have made a URL Group and add it to the Negative Rules for non registers user on Search, like /?=s and then it works perfect

I can't get it to work on sub pages. Like I have one on https://sseu.securitasconcepts.com/business-case/test-2/?print=pdf

I would like a rule like: https://sseu.securitasconcepts.com/business-case/*/?print=pdf

In other words, I want to hide all Posts under business-cases is this possible?

All the best
