Tags, but the opposite

Maybe this plugin can help you: New Plugin: Select-A-Structure

I used it to have a selectbox with authors in my blog post blueprint like this:

  creator:
    icon: user
    label:
      de: Autor
      en: Author
    type: selectastructure
    structurepage: blog
    structurefield: authors
    optionkey: name

The authors are managed on the blog overview in a structure field:

  authors:
    label:
      de: Autoren
      en: Authors
    type: structure
    entry: >
      {{name}}
    fields:
      name:
        label:
          de: Name
          en: Name
        type: text
      image:
        label:
          de: Bild
          en: Image
        type: image
      info:
        label:
          de: Informationen
          en: Informations
        type: textarea

Imagine authors as questions and store them per page again in a structure field (“…to answer one or more questions…”)?

it might be i don’t completely understand your needs, especially:
