Task lists in VP UML?


in my projects, I often need to monitor and control tasks, which are linked to UML models (e.g. “diagramA should be done on 1st Feb 2008” or “RequirementB must be approved on 15th Jan 2008” etc.). So, I want a list of tasks (description, due date, responsible person etc.), which I can edit inside VP UML.

Is there any option or idea, how to track tasks in VP UML ?
