TPlanner Row Hieght

I'm using the Tplanner component, with vertically the names of employees, and horizontally the dates of the week/month.

How can i set the height of specific rows?
For employeeA the row could be 20 px height, and for EmployeeB 40 px height.


planner.PositionWidths[position]: integer;

shoot! that easy, thnx ;-)
