I am creating a Lens Visualization on Kibana 7.17  
When I try to customize my timestamp to aggregate data on several days, I can do it easily

However, when I try to aggregate my data on several weeks, months or years, it is greyed and reset to 1. I cannot aggregate for instance on 3 months to have a quater.

The same problem appears on weeks, and years.

Hi Pat. According to the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/8.6/search-aggregations-bucket-datehistogram-aggregation.html#calendar_intervals) not possible for Elasticsearch to have a `calendar_interval` of multiple quantities. That is why Lens is disabling the field.

Instead of 3 months you may try using `quarter` to get an interval of one quarter.
