Custom calendar / agenda event filtering

I would like to be able to filter out events with a custom partial text match. For example, my work calendar will have an “OOO” (out of office) meeting on every vacation day. Due to my workflow, I have many calendars (for each customer), so the result is my agenda is full of “OOO” meetings.

The same principle could be useful for other recurring events you don’t care about when quickly checking your agenda, but are mainly useful to block certain times when scheduling new events.

Other calendar widgets like “Calendar Widget: Month/Agenda“ & “Your Calendar Widget“ have had this functionality for years.
