PlanningCalendar Appointments not resizable to the left side

Hey, are there any plans to make the left side of appointments inside the PlanningCalendar resizable?
The PlanningCalendarRow has the appointmentResize Optionm but it only works for the right side of the appointment. I find this to be inconsistent in the design. The SinglePlanningCalendar allows resizing to both sides (up and down).

OpenUI5 version:
Any

Browser/version (+device/version):
Any

Any other tested browsers/devices(OK/FAIL):
X

URL (minimal example if possible):
https://sapui5.hana.ondemand.com/sdk/#/entity/sap.m.PlanningCalendar/sample/sap.m.sample.PlanningCalendarDnD

User/password (if required and possible - do not post any confidential information here):

Steps to reproduce the problem:

1. Go to left side of Appointment
2. Try resizing it to the left

What is the expected result?
Appointment gets resized to the left and the StartDate gets updated

What happens instead?
Mouse cursor doesn't change and the left side is not draggable
