You can create an event on the dashboard.
And you need to choose an item (a listing). then listings are all you (the user) created. You can’t choose others listings.
You will see an event title and listing name on the event list.
When you click the listing name, you will see the event information.
Other users can also see the event on the listing as well.
It basically places on the listing. ( except grid style at this moment)
