You can't.  <preserveintarget> "wins" indeed, by design, as the task is
currently implemented.
You'd need to add a (e.g.) "unlessAncestorDirIsRemoved" attribute on
<preserveintarget>
to "weaken"
<preserveintarget>, with associated logic of course.

Or you work around by copying/syncing your "preserved" files in to a 3rd
directory.
Sync as before, w/o the <preserveintarget> elements.
And "restore" those back, provided their directory still exists. I think
it's possible with a selector
and mapper to figure out of the "preserved" files should be restored (not
easy, but possible).

FWIW. --DD
