[Plugin: WP-dTree] Post counts

Hi,
Is it possible to include posts which are folders. At the moment, dtree does not count post which are in the sub folders.

For instance at the moment dtree show as:
[+] Parents category (2)
[+] child category (3)
[+] grandchild category (20)

Is it possible to show the post beneath as well?
[+] Parents category (25)
[+] child category (23)
[+] grandchild category (20)

Thank you.
