How to filter the templates of a pages section?

i have a pages section with three different types of blueprints.

      - message
      - message-de
      - message-en
    status: all

i would like to enable an editor to filter the pages shown by filter the blueprint templates.
is there some kind of plugin, or can we extend a pages section, add some kind of toggle to filter the template list? would that also effects the ‘add-dialog’?

Maybe you can achieve this with the Pagetable plugin:

Uhh, that looks promising. I will have a look. Thank you already!
