Calendar option: block x minutes (e.g. 5) before and after appointments in free (available) time as timepuffer

People with many (online) meetings have the problem, that they have no time to switch from appointment to appointment and to change the (online) room.

It would be fine, if there would be an option e.g. in the calendarprofile and/or a button in the meeting document itself, where one can add some pre defined free time.

E.g. I have a meeting from 1 pm till 2 pm and my calendar shows some free time from 2 pm till 3 pm, I have no time to change/rest etc.

If I could add some timeslot before and after an appointment, I could block my calendar free time for e.g. 5 minutes, so that next invitations and in that way the following meetings would start after that pause.
