How to create a Task from a calendar Event.
1. Select '+Add New' and 'Event'.
2. Fill in the calendar Event details. Don't click 'Save event' just yet!
3. Once you've added the Event details, select 'Copy to Task'.
The Event details entered previously now appear here as you create your new Task.
NOTE: If you leave the 'Assigned To/Billing User' field blank, this Task will automatically be assigned to your username.
