Root page as option in query

Hello,
Is is possible to pass the root of the site into a pages query in a blueprint?
I am trying to provide a way to select from top level, invisible pages.
Passing /, root, default leads to an error.

pagelink1:
      label: Top Link
      type: select
      options: query
      query:
        page: /
        fetch: children
        template: sitepage
        value: '{{title}}'
        text: '{{title}}'

If you are using Kirby 2.1 you could try this:

...
query: 
  page: home
  fetch: invisibleSiblings
...

But I think this won’t work, if you want to get deeper than the first level. I didn’t try it, just a guess …

I don’t think this works, but you can go up in the tree:

pagelink1:
	label: Top Link
	type: select
	options: query
	query:
	  page: ../../
	  fetch: children
         ...
       

depending on your level, you have to climb up as needed … The / notation is supposed to work but doesn’t … https://github.com/getkirby/panel/issues/392

I am at the top of the hierarchy so going back does not work.
I just stuffed the pages in a stub container page and went ahead. Good to know that the issue is already fixed.
Thank you!
