I've noticed this in the manual.
Use Garmin connect to create courses and course points and transfer them to your Forerunner.
Hopefully this will be something that will be added in GC's next update, since it is not available yet.
The owner's manual says courses and custom workouts can be created in Garmin Connect but I don't see this feature in GC nor is there any "help" on the subject. Thanks for pointing me in the right direction.
