We do not currently have a preference to group meetings, which is a technique to avoid having gaps in your schedule. However, there are some work-arounds to better-cluster your meetings.
Set up Meeting Templates
You can create a Meeting Template for meetings you do regularly, and you can limit the times of day that meeting can be scheduled.
You can also cue Scheduler, Amy, and Andrew when you send in meeting requests to let them know if they need to be scheduled during a certain time period like this
"Amy, please set this up between 2 and 4 on a Thursday"
“Andrew, please find us a time on Wednesday afternoon for a video conference”
“Scheduler, schedule a call tomorrow at either 1pm or 2:30pm”
They will then prioritize scheduling that meeting in the specified block of time. You should also make sure you’ve set the "breather time" between meetings at 0 minutes so that Scheduler, Amy and Andrew can more easily set meetings back to back.
