Default none/dummy option for template variables?

Enable the Include All option for a template variable automatically makes that the default value. This can make things unusable for some dashboards since too expensive to load. Saving the template values with the dashboard is an ok workaround, but still a bit klunky in that we have to select arbitrary values that may confuse future visitors. Plus, it breaks down when the variable is populated by a templated data source: changing the data source resets the dependent variables back to All which causes the browser to catch fire.

Has anyone found a more elegant workaround? Thanks!

Did you figure this out? I’m looking for a similar feature where it defaults to “None”. I’d like a user to choose All or specific options.

Unfortunately, I was not able to find a good solution.

I’m also looking for this feature. I will see if I can modify Grafana.
