Auto assigning to a user on transition from one Kanban step

Question

I'm using Jira Agile on ONDemand and I have defined my own workflow so I can auto assign issues to users when tasks are dragged between Kanban steps.  I'd like to do two things.  I have two steps that I'd like to remove the assigned user (or assign the task to unassigned) when the user drags a task to one of my steps.  And I'd like to auto assign the user to a specific user when the task is dragged to another step.  However, in the Post Functions I don't see an option to assign to a specific user or remove the assigned user.  How can I do this?
