Clocktable :formatter to record time in hours or work-days

[William Denton]

I've been clocking in and out of a project for a few months and now it's over. 
I tagged each entry with "search", so a brief clocktable report looks like this:

#+BEGIN: clocktable :maxlevel 1 :scope file :tags t :match "search"
#+CAPTION: Clock summary at [2023-04-11 Tue 13:48]
| Tags | Headline          |    Time |
|------+-------------------+---------|
|      | Total time        | 4d 6:23 |
|------+-------------------+---------|
|      | 2022-09 September |    0:38 |
|      | 2022-10 October   |    2:46 |
|      | 2022-11 November  |    7:41 |
|      | 2022-12 December  |   10:41 |
|      | 2023-01 January   |   10:16 |
|      | 2023-02 February  | 1d 3:56 |
|      | 2023-03 March     | 1d 3:47 |
|      | 2023-04 April     |   14:38 |
#+END

How could I format the Time column in hours?  How could I format it to hours/8, 
rounded, to represent work-days?  I only want this formatting for this table, I 
have other clocktables in the same file I don't want to change.

I've read about clocktables and the :formatter option, which I assume is what 
will do it, but I can't find any helpful examples so I'm stuck.


Thanks for any help,

Bill
