Customize hover information

Hi ,

I am using Grafana 8.3.2 verion to plotting the data and my data source is Elasticsearch.

Is there any way to populate extra variable value in hover information. Currently my hover information carrying the x-axis value (date histogram) and metric value that I am using for that graph.

I have a keyword (named build) under the same index and I want to populate the value of keyword build as well with hover information. The value of build is different for each point (date)

Here I want to populate build keyword value along with datetime:

On 13th result
2022-03-13 05:30:00 / 123456
on 14th result
2022-03-14 05:30:00 / 123856

Any idea on this ? Can we achieve this through annotation ?
