Copy/paste appointments in Calendar by dragging them to new date

It would be nice if we could copy/paste appointments in calendar by just pressing the CTRL key on the keyboard and dragging the appointment to another date. It is possible in Outlook and it is very convenient

This is REALLY a missing function! There is no “copy&paste” in the popup-menu when you click on an appointment, too! It would be great to select/deselect multiple appointments by holding CTRL pressed and move them. Press CTRL+Shift copy all selected…

For as great as this app is, why is that not a feature???  CTRL-dragging appointments is COMMON in Outlook.
