What is the best way to organize role dependencies?

Question

Ansible

There is such a structure of roles:

roles/
  /app1
  /app2
  ...
  /appN
  /nginx-webserver
      templates/
         nginx_app_site.j2
  playbook_app1.yml
  playbook_app2.yml
  ...
  playbook_appN.yml

All applications are deployed on the same server.
The bottom line is to use the nginx_app_site.j2 template with different domains. That is, you need to call the nginx-webserver role with different domains from each playbook (nginx_domain: appN.com) . What is the best way to do this? Use import_role or call nginx-webserver as a separate role in the playbook along with the appN role?
