Hum, i had to read corrrectly.
This plugin is for shipment.
It's better to not use an existing plugin, but write a new one. you can copy "standard' plugin in a new folder and change class + folder name and add your needs inside this new plugin.
Of course, you need to know PHP and a little VM+Joomla coding.
