Is it possible (or possible in future) to set some sort of lisp variable (or item property) to prevent certain agenda items from generating a notification beep?
In my current use case, it would be helpful to do something like
(set! agenda-nonotify-files '("my_wifes_exported_calendar.org"))
so that I can see these events on the agenda but not be beeped about them. (I do want to be beeped about other scheduled events on the agenda.)
Since in my use case the file "my_wifes_exported_calendar.org" is computer-generated, I would not mind adding some sort of property or tag to every item that should not generate a notification, if that turns out to be easier to implement (or for all I know may already be implemented).
A good suggestion - I'll make a note to add in a future update.
