Thank you so much! This will be very useful.

One related question - I'm including another subtree (I'm using 8.3beta) using

   #+INCLUDE: "playground.org::*Contents" :only-contents t

but it seems I cannot access the property of the parent heading inside the included subtree. (Using {{{property(EXPORT_Variable)}}} to access the parent property). Is this not possible?

Thank you so much,

Joon
