Dynamically changing URL in reader

Hi,

I have an URL that I’d like to read in, but it contains the current date and thus is being updated everyday. 

How may I change the URL within the reader so that it’s automatically up-to-date?

I’ve tried define a user parameter as a URL but I don’t manage to make it dynamic there. I thought I could replace the date e.g. 2024-11-05 with @DateTimeFormat(@DateTimeNow(),%Y-%m-%d) in the Default Value URL but it doesn’t work.

Any help appreciated!
