Stretching schedule borders using PythonShelll

I am trying to find a way to manipulate schedule’s borders by PythonShell after placing a schedule on a sheet.
We usually do have a title block with some limits placed on a sheet, and a schedule with a very long height. So we tap that little z-symbol on a schedule’s border to clip it in half, then fit one part in a title block and drag out another.
The question is: how can I do the same things using Revit API from PythonShell? What namespaces contain commands and methods to move that dots? All I’ve found concerns schedule’s formatting, filtering, adding columns, whatever but not editing its size. So where could it be?
