Hi @hj98,
From an automated/dynamic way, that is correct. Currently there’s no QuickSight feature that easily sets up this type of bucket creation, if you were to setup a formula that checks if the date fell (let’s say, within 1 day…) it would only have the last datapoint to reference, so if you had more than two datapoints, it would not be able to programmatically group.
It would be nice for a feature to be available that can assist in bucket creation so I’ll mark this as a feature request.
Let me know if you have any additional questions
