Repeat Bookings
When creating recurring meetings (none integrated rooms only) you can manage how many weeks in advance users can book with this setting.
Head over to Settings > Meeting Rooms > Meeting Rules (https://portal.clearooms.com/settings/meeting-rooms/rules).
From here, you can toggle on and off the 'Repeat Booking' option and set the duration in weeks.
Make sure to click 'Save' at the bottom of this page for the effects to update.
