[Orgmode] Re: add a whole directory as one item to refile targets

Yes it is supposed to be a directory...

I have org files in many directorys... about like so:
 reference/emacs/emacs.org
 reference/eros/eros.org
 reference/Avalon/Avalon.org
 reference/Gimp/Gimp.org
 reference/office/office.org
 reference/home/home.org
 reference/poems/poems.org
...

What would be a smart way to get a headline from the file inbox.org
named "* Erich Fried poems" to poems.org?
Considering that poems.org is not part of the agenda nor a refile target.

What I am doing until now is:
 folding the headline (tab)
 cutting the headline (C-k)
 making a split screen (C-x 2)
 changing buffer (C-x o)
 opening poems.org (C-x C-f "reference/poems/poems.org")
 pasting headline (C-y)
 changing buffer (C-x o)
 removing split view (C-x 1)

Poems.org is not part of the agenda because it is reference material
and not an active file.
It is also not a refile target because I would have to make every .org
file in all subdirectories a refile target and sometimes the
appropriate file does not yet exist, in which case I need to create
it.

Any ideas?
Do I need to further try to make clear what I mean?
