Not sure about the cab install provided as this is included as a package in the kitchen I'm using...
there is no feature to add customized sounds to it.

But the sound files are merely wav files. So you could extract the cab on a computer, replace the wav files (there are two for each sound and in and out sound) and edit the registry to set the names. Then cab it back up and install.

Just rename the wav files to the same names as in the cab (xwav I believe) copy and your good to go.
