puh ... it would of cause be possible to write emacs lisp to find, extract
and process the date info from the parent tree's :raw-value, but I must
admit I don't want to do it, since it is just extra work required by
un-idiomatic use of Org-mode. 

You have all the means to create a nice logical project file out-of-the
box with Org-mode, use tags, timestamps, deadlines, properties etc and
then extract selected info via the agenda. 

Otherwise you need to write custom elisp yourself or find somebody who
does it for you ...
