children macro that includes the page, not just toc

I have an FAQ, 3 level deep hierarchy.
I use the children macro to get a nice dynamic toc for the confluence users.

problem: I need to export to pdf this subset. But the children macro only creates a toc index, does not include the sub pages body and I don't see a way to do it.

Do not reply that I can use the export space feature. that is not a good option. I want to have a confluence page that people can go to and click on the PDF icon to get the full FAQ and send to customer.
