2 Class Template Parameters

I’ve read this tutorial: http://resource.visual-paradigm.com/uml_diagrams/class_diagram/drawing_class_with_template_parameter.html#adding_template_parameter_-_an_uml_approach.

But what to do if I want to have 2 template parameters?

The Instant generator changes ex.: List<Costumer, Car> to List<Costumer__Car>.

How I can use class with two template parameters. Maybe I forgot to switch an option, or something?

Thanks for any help!
