Multiple files in one collection?

[regalstreak]

Is it possible to group multiple files inside one collection?

I have

content:
  # Site Configuration
  - name: siteConfig
    label: Site Configuration
    type: file
    path: src/content/site/config.md
    fields:....
  # Home Page Content
  - name: siteHomePage
    label: Site - Home Page
    type: file
    path: src/content/site/home.md
    fields:....

  # Page Content
  - name: sitePlaybookPage
    label: Site - Playbook Page
    type: file
    path: src/content/site/playbook.md
    fields: ....

Is it possible to view the collection view (on the sidebar it shows "Site") and inside there would be these files only, and no option to add a new entry?
