PhotoStream as an Event

I was able to create an Event of the month's PhotoStream by:

1. Choosing the Photostream you want by selecting on the #photos on the grey bar (this highlights the photos in that month's PhotoStream)

2. Flag those photos (Command FullStop)

3. Go to the Events Dropdown Menu and select "Create an Event from Flagged Photos"

4. This creates an "Untitled Event" whereby you can then continue to manage your photos as per usual

5. Remember to Unflag the photos highlighted (Command FullStop)

6. This helps you "fix" duplicate photos in your Library
