Parent not always showing when listable

[meandersen]

I have collection called pages, I have set Parent listable to Shown by default but it's not always shown in the list.
It is crucial to have it, because there can be multiple pages with the same title but with different parents, and it will be hard to link to the correct entry.

Is there a way to make sure parent is always shown in the list, or a way to display the actual route of the page and not just the slug.
