I'm using the default newsletter page template, but when clicking each article, I want it to direct to the PDF link of the actual newsletter instead of the article page within Squarespace. I don't want my users to have to click 2 links before being able to open the newsletter, but I can't seem to find a way to add a custom link with code.

Thank you!

Yes.
You can add the link to the page itself and through code get the link from each page and add it to the main page on each item.
