TPlanner Item Size

TPlanner: <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

SideBar->Position=spTop<o:p></o:p>

Regardless if there is only (1) or (many) Planner->Items,
I want to have them consistantly at a specific size(height) <o:p></o:p>

Is there a property to control the size “Height” of the displayed ‘Item’ horizontal’
bar ?<o:p></o:p>

Set: 
Planner.PositionWidth = desired_height;

Planner.PositionAutoSize = true;
