In table views and in the Selected Points window, the Locate in Google Earth context menu item has a submenu item named Options. If you choose that instead of Fly direct, you can specify the attribute fields (if any) to be used for constructing the descriptions that appear in GE when the user left-clicks a placemark icon. The placemark symbols for multiple-point exports and single-point exports can be specified as two URLs via a preference setting. (See Google Earth (KML) launch options.) The two screenshots below show the KML Options dialog followed by what might appear in Google Earth.
Note that in this example the COMMENTS field is included in the KML, which for this particular project would likely be a poor choice. A large report can cause too long of a delay after the click and before the description window appears. Also, the dialog itself doesn't yet provide a way to modify the descriptions. For now we can only choose the fields that will be included and preview the result.
