What problem do you have with the above?  Can you give us a minimal

Date trees can be tricky.  As far as I understand, you want to add a
subheading to entries for a day.  I do not think file+datetree can do
that.  I would recommend you try file+function instead.  It should be
easy to implement.  You could use org-map-entries to find the headline
in your headline finding function.

Hope this helps,
