How to export two or more geostructs using kmlwrite()

I am a relatively new user of the mapping toolbox.

I have two geostructs with distinct data, and different fields. Each represents point data, and I want to display both in Google Earth using a single file.

Currently I can create two separate KML files like this:

                kmlwrite(kml_file1,data1,'Icon',i1)
                kmlwrite(kml_file2,data2,'Icon',i2)

And open them separately in Google Earth.

I want to do something like this:

                kmlwrite(kml_file,data1,'Icon',i1,data2,'Icon',i2)

Where both structures are saved in the KML file with their own separate icons, descriptions etc.

Grateful for any help I can get.
