Morgen Assist's Calendar Propagation workflow is a simple way to add events from one calendar to another. The events are added will be marked as Private Events, blocking the time without sharing the details across multiple calendars.
This is a great way to block time for private events on your work calendar to avoid double booking.
Here's how to use this workflow, and if you feel inclined, customize it further using Nerd Mode.
