[O] tasks, clocks, and notes

[hymie!]

Greetings.

I have a funny feeling I asked this before, but I can't remember and I
couldn't find it in a search.

So let's say I have a task -- fix a computer.  I add some memory, I test the
new memory and that doesn't solve the problem, and then I finally figure out
it was the video driver.

I could log that this way:

* fix the computer
**  added memory to the machine
    CLOCK: [2015-01-28 Wed 12:36] -- [2015-01-28 Wed 13:14]
**  memory didn't resolve the problem
    CLOCK: [2015-01-28 Wed 13:28] -- [2015-01-28 Wed 13:53]
**  finally found it -- it was the video driver
    CLOCK: [2015-01-29 Thu 09:12] -- [2015-01-29 The 11:30]

but then my Agenda will have pretty disjoint notes about "added memory to
the machine".  I'd prefer that the Agenda either say "fix the computer"
or (even better) "fix the computer -- added memory to the machine".

Is there something I can do that would add "notes" to an individual clock
entry, something like

* fix the computer
    CLOCK: [2015-01-28 Wed 12:36] -- [2015-01-28 Wed 13:14]
    added memory to the machine
    CLOCK: [2015-01-28 Wed 13:28] -- [2015-01-28 Wed 13:53]
    memory didn't resolve the problem
    CLOCK: [2015-01-29 Thu 09:12] -- [2015-01-29 The 11:30]
    finally found it -- it was the video driver

that would still leave the clock lines "attached" to the main task, but
still keep some individual notes about the various pieces of the task?
