How do we use the same article (file) in the group listing and on the Vacancies page as required?

•    On the Publishing tab of the Group Article set Author alias to ‘vacancies’
•    Then a module, of a type Articles – Category (at present ‘VacanciesCategoryMenu’)
•    Menu Assignment tab, as required
•    Filtering options tab, Category as ‘ – Interest and Course Groups Category’
Author Alias Filtering Type, Inclusive (use Exclusive if you wanted articles where there was no Author Alias)
Author Alias, ‘vacancies’

Each title of a short article is prefixed with a number to segment the articles (but not consecutive within the segment so additions can be fitted in).
