Blueprint section parent query

The CMS Questions

I was wondering that too!

But I think this would need a query: option besides the existing parent: as your filterBy example would lead to multiple parent elements.

I found this issue/idea: https://github.com/getkirby/ideas/issues/28

EDIT:

Seems like something like this is already possible:

pages:
  type: pages
  headline: Notes
  parent: site.index.findBy("template", "notes")
