TL;DR, I'd like a configurable time on my calendar that shows me as "busy" that doesn't show up on calendars.
I want to ensure that nobody attempts to book meetings between 1pm and 2pm so that I can take my lunch break.
I've created a recurrent weekday appointment, but this shows up in Outlook and on my iPhone calendars as an event, which clutters up my daily views and gives a false impression that I have a meeting every day.
Ideally I'm looking for something like the start/end times for a work-day. Is this possible?
