Can we support custom visualizations on a subset of graphs?

I’d like to take advantage of the custom visualizations in Looker. In particular, I am interested in the Sankey diagram for a subset of graphs.

If we implement the sankey diagram with a custom visualization in the admin console (docs), does that mean the custom viz is enabled across our instance?

Is it possible to enable a custom viz for just a subset of graphs? eg, Use a sankey diagram in this use case without surfacing it as an option as part of every explore.

@Sebastian_Heyneman I don’t believe it’s currently possible to limit the visibility of custom visualizations to a particular group of users, particular explore, etc. In our instance, we’ve labeled custom visualizations with “(Beta)” to help minimize end-user friction if custom visuals don’t function as expected.
