Include a substring from a series name in a data link

I’m sending per-host metrics into Graphite from collectd. The metric names look like this:


I have a dashboard with a bar gauge panel showing which disks are closest to being full:

highestCurrent(sortByTotal(aliasByNode(host.*.df.*.percent_bytes.used, 1, 3)), 10)

I’d like to add a data link to another dashboard showing details about the host:

Is there a way to extract the host name graphite-01 from the series name to include in the data link?
