I'm pretty sure I don't follow what you're asking so I'll just take a guess that you're looking for this.

Hi Rob, thanks for your reply. Let me try to clarify... I have a form that contains a URL field. The inputed value, in this case from imported CSV tables, is then added to a View as a button or a link. However, I need to append "?dl=1" to the end of the original URL value, so that the href on the rendered button code contains the URL with the query string.  In terms of my ultimate puropoe, I am trying to force downloads instead of rendering the link in a browser. The above query string does that. But if you have another way to do that, let me know. Thx

Add a new field and add your text as the default value.  You can then add the https://google.com/[134] and that next text will be were [134] is.
