One page query in a page section

Hi,
I’m wondering, I’d like to display one page for my client to edit.
The best thing I found is :

sections:
  content:
    type: pages
    parent: site.find("cv")

In my content folder the one I’d like to fetch is located here:
content / cv / cv.txt
But
parent: site.find("cv") queries inside that folder. And it requires me to do something like
content/cv/cv/cv.txt (so generates me a bad url like example.com/cv/cv

How to avoid that and stick to the original situation, but query only the needed page ?

sections:
  content:
    type: pages
    template: cv

My bad. Thanks!
