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:

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?
