Sure, but if you touch each object anyway, you dont need the catalog.
I can think of two ways to solve it a bit cleaner:
Record the title in the catalog, you can ilteratively search
for the sub paths which should give you only one result - the folder
along with its title.
The other way would be a method which returns your path title chain
as a string (in the ZClass) and catalog it with every object.
