Filters Per Calendar

[broyuken]

I would like to be able to have filters on specific calendars. My use cases are the following.

I have a work calendar, but I don't want all of my work events to show up on the family calendar. I only want ones that match specific subjects, such as "Company Holiday" or "OOTO".

The other use case is my wife is a fitness instructor and she has a calendar that shows which instructor is teaching that day. I only want those events to show up if she is the one teaching.

But again, the important part here is I want to filter these events IN, but only from certain calendars. If I set a filter as it is today, ONLY those events would show up, and all the events on my personal calendars wouldn't match those filters and would not show up.
