Well, the kml file is the most logical location, it's a straight forward
html-ish text file. Never looked at the kmz that close, but I assume it's a
more comressed version. (probably pkzipped by the looks of it)

If you save your file as a kml, close GE, then open the kml
with notepad you will see how it's formatted. Then stick something
like this inbetween existing <placemark></placemark> code

<Placemark>
<name>groom lake</name>
<LookAt>
<longitude>-115.8126382174268</longitude>
<latitude>37.25512234152102</latitude>
<range>20103.15543326131</range>
<tilt>0.2080558487320975</tilt>
<heading>-5.405135213921768</heading>
</LookAt>
<styleUrl>root://styleMaps#default+nicon=0x307+hicon=0x317</styleUrl>
<Point>
<coordinates>-115.8126382174268,37.25512234152102,0</coordinates>
</Point>
</Placemark>

Now save the kml, start GE, and load that file.

It's not elegant.
