Drawing lines on map

I’m new to this plugin, so I haven’t tried this, but I believe you can do this by creating a line in Google’s My Places, and when you save the map, there appeares a small link for “KML”. You copy and paste that KML into the KML input field in the plugin’s Shortcode Builder interface.

When you build your map (in Google My Places), you can enter text for the dialog bubbles. I wonder if those bubble texts are preserved in the KML…? (In case anyone reading this knows the answer).
