[Orgmode] Only Clock in Top-Level Task

[Markus Heller]

Hello,

This is what my project.org looks like:

* STARTED My Project                           :NEXT:   
  :LOGBOOK:...

** TODO Task 1 [0/2]
*** TODO Sub-Task 1
*** TODO Sub-Task 2

This is what I'd like to do:

I'd like to be able to clock in from Task 1, Sub-Task 1, or Sub-Task 2, 
but make org-mode add the clock entries into the :LOGBOOK: of My 
Project, i.e. the top-level task/project.  In other words, I'm not 
interested in keeping track of how much time I spent on Task 1, or any 
of the sub-tasks, I'm only interested in the time I've spent on working 
on My Project.

Is there anyway to do this?

Thanks and Cheers
Markus
