Hey Michael,
Thanks for reaching out to us!
You should be able to accomplish this by modifying the “Author” of the event and switching it to the Coordinator that you would like to be able to manage the event.
To do this, you’ll see an “Author” box on the event edit screen with a dropdown of all the potential users that you can assign as the event author. If you don’t see this box, select the “Screen Options” tab while on the event edit screen within your dashboard and ensure that the option is selected.
Let me know if this helps.
Thanks!
