appending node based materials (does not append node tree) ?

[zach]

Can't link/append material created in node editor, node tree is missing, after appending node tree separately material works fine.
Is it bug or missing function?

Officially will become possible with 2.79 release... recently added: Datablock ID Properties Patch ✓ In Master

Critical forward-compatibility warning: Any .blend file using new data-block custom properties saved in Blender 2.79 and beyond will crash when opened with Blender 2.78c and any previous releases (follow link above for more details).
