HP Service Manager automatically open Incident Task with corresponding category and workflow

Hi,

I have 3 different Incident categories, each has his own workflow. Now i also have 3 different Incident Task categories with corresponding workflows. Question is: Creating new Incident Task, how to open from Incident automatically Task with correct category and workflow? I don't want user to choose task category every time he creates new task.
Using SM9.41.

Regards,
Ainer
