OK, I think I understand. In my setup all the todo are in the same
file, so it should help.

So I'll rephrase my question: how can I set-up an agenda custom view
such that it shows only the TODO from one file that have a given tag, as
well as their subtrees? (I want to use an agenda custom view because the
agenda export command are really nice and easy to use programatically.)
