Print Structure field value within help text

Hey there,

I have a structure definition with a slug field and an info field, which is used in a custom route.
Now I want to print the route url as a custom link to the users. Is there a way to access the slug field value within the help text?

  label: Promotion links
  type: structure
      type: slug
      required: true
      before: "{{ site.url }}/business/"
      type: info
      theme: positive
      text: "Your promotion link: <br>{{ site.url }}/promotion/{{ ??? }}"

Thanks a lot!

I don’t think this is possible.
