There is no real straightforward way to do that, but you can include
queries in the templating. As a starting point, something like the
following could work as an annotation:
```
description: 'Disk {{$labels.volume}} on {{$labels.instance}} is {{$value |
humanize}}% full. Total size is {{ printf
`windows_logical_disk_size_bytes{instance="%s",volume="%s"}` $labels.instance
$labels.volume | query | first | humanize }} bytes.'
```
