using slugs instead of filename with document driven mode

[snimavat]

By default it uses file name,
How can i get slugs to work with document driven mode.

So if i have

slug: nuxt-tutorial in /blog/1.post-one.md

I want the url to be /blog/nuxt-tutorial

I tried putting a catch-all page at /pages/blog/[...slug].vue however tht page does not execute at all

Any ideas ?
I want to use document driven for other parts, except blog, where i want routes to be based on slugs
