Hi there @Marty
Unfortunately, there is no way to copy specific events between widgets. You can vote for this idea in our Wishlist - Copy events between calendars.
However, I see that my colleague Apollonia has already contacted you in a support ticket, and as she said, you can duplicate the whole widget. For this, click on the three dots next to the widget → Duplicate :
The copy will contain all the events and settings of the original. You can change the copy to your liking
