It wouldn't be random, but user selected. I have imported calendars for church, daughter's soccer team, some clubs and hobby events, etc. Some of them I leave disabled unless/until I want to check them specifically, but it's nice to have them right in my calendar instead of having to go to the right page or app to see different schedules.
