Variable in dashboard description

[jawebb]

What is the best way to have the <description> tag in a dashboard reference a variable? Let's say that I want to display a disclaimer or other information for a set of dashboards and don't wish to edit each one as often as it changes. I know I could probably use HTML or CSS for this, but wanted to know if anyone has a better way or if splunk supports this natively.

Thanks

I'm doing this with a saved search:

....
| eval comment="Disclaimer"
| stats values(comment) 

This is configured as single value vizualisation and can be added as dashboard panel. To update the displayed information in all dashboards just edit the | eval comment="Disclaimer" in the saved search.
