Hello all,
  I have looked at many invoicing solutions in org-mode. I find them to be
a bit tedious for my needs.

I really like clocktable's simplicity. However, I would like to display,
say the 3rd level headline alone.

* foo 1
** foo 2
*** bar 1
:LOGBOOK:
CLOCK: [2017-07-21 Fri 12:00]--[2017-07-21 Fri 13:00] => 01:00
:END:


The corresponding clocktable is

#+TBLNAME: clocktable
#+BEGIN: clocktable :maxlevel 3 :scope ("todo.org") :block 2017-07
#+CAPTION: Clock summary at [2017-07-22 Sat 23:24], for July 2017.

| File     | Headline         | Time    |       |       |
|----------+------------------+---------+-------+-------|
|          | ALL *Total time* | *01:00* |       |       |
|----------+------------------+---------+-------+-------|
| todo.org | *File time*      | *01:00* |       |       |
|          | foo 1            | 01:00   |       |       |
|          | \_  foo2         |         | 01:00 |       |
|          | \_    bar 1      |         |       | 01:00 |
#+END:

Is it possible for just the "bar 1" entry alone to show up on the table
without the higher level headlines in my org clocktable?

Thanks and have a great day!
Bala
