If you need to quickly change the booking length of some slots, you can do so through a quick deviation.
Go into the booking, click on "select multiple" in the top right corner and click on the times you want to change. Note! Keep in mind that the start and end time must have space for the new booking, for example, if you have 60-minute bookings and want to make a 90-minute booking, you must mark two times in the time booking. There will then be a 90-minute booking and a gap of 30 minutes. You can fill the gap by creating two 90-minute times instead (by selecting three times).
Select "deviations" and "create deviation".
The deviation is preset with all parameters except time length, it must be set as desired. To create 90-minute times, set it to 1:30 (one hour and thirty minutes).
Then click on "next step", check that the deviation adjusts as desired and click on save.
To close bookings, select "deviations" and "close times" after selecting the times to be changed.
