If you want to manually add a message to a thread you need to copy the
Message-ID value from the parent message and add it to the
References header of the child message. Of course, you would need to add the
References header if it does not already exist in the child message.

So:

* select the parent message, and use /View/Show all headers
* copy the Message-ID value
* open the child message with a text editor
  The easiest way to do this is with an Action, such as:
  Menu Name: Open With/kate
  Command: kate -n %f&
  (It's the %f& which is important here; you will use your favoured text
  editor)
* Then paste the Message-ID value into the References header (or create it)
  and save it.
* finally, use /View/Update summary
