Exclude calendars from notifications and upcoming events

I've subscribed to some calendars, that I want to stay updated on, but they are not important for my daily business, but I get notifications for them all the time. Also the upcoming events feature that I love includes these calendars as well.

I don't want to enable and disable these calendars every time. So they should show up in the calendar, when I open Morgen, but I'd like to exclude them from notifications and upcoming events.

It would be such a nice feature. Thank you! :)
