At the moment I get something like this:
* Hours Today
#+BEGIN: clocktable :maxlevel 2 :scope subtree
Clock summary at [2013-11-04 Mon 15:53]

| Headline                      | Time   |      |
|-------------------------------+--------+------|
| *Total time*                  | *6:35* |      |
|-------------------------------+--------+------|
| Hours Today                   | 6:35   |      |
| Workshop shell scripting      |        | 2:12 |
| Security Intake               |        | 2:39 |
| Internal Project              |        | 1:44 |
#+END:

*** Workshop shell scripting
    CLOCK: [2013-11-04 Mon 13:49]--[2013-11-04 Mon 13:56] =>  0:07
    CLOCK: [2013-11-04 Mon 11:03]--[2013-11-04 Mon 11:55] =>  0:52
    CLOCK: [2013-11-04 Mon 08:45]--[2013-11-04 Mon 09:58] =>  1:13

    CLOCK: [2013-11-04 Mon 13:56]--[2013-11-04 Mon 14:01] =>  0:05
    CLOCK: [2013-11-04 Mon 11:55]--[2013-11-04 Mon 13:49] =>  1:54

    CLOCK: [2013-11-04 Mon 14:26]--[2013-11-04 Mon 15:05] =>  0:39
    CLOCK: [2013-11-04 Mon 09:58]--[2013-11-04 Mon 11:03] =>  1:05


But because ‘Hours Today’ already is a summation, I would like to get something like this:
* Hours Today
#+BEGIN: clocktable :maxlevel 2 :scope subtree
Clock summary at [2013-11-04 Mon 15:53]

|-------------------------------+--------+------|
| Hours Today                   | 6:35   |      |
|-------------------------------+--------+------|
| Workshop shell scripting      |        | 2:12 |
| Security Intake               |        | 2:39 |
| Internal Project              |        | 1:44 |
|-------------------------------+--------+------|

Is that possible?
