Custom task type in Modeler

Hello there,

my question is that is there a way to add custom task types to the Camunda Modeler?
My idea is to add a new button to the palette which says for example “Create HelloWorld Task” and this task logs “Hello World” to the console. It can be for example a service task, I just want to hide that information, so the user cannot see that a service task is running in the background.
Do you think it is possible? If it is, can I deploy this diagram through the Modeler?

Thank you for your help!!
