It looks like some people may have figured this out already (?) but after watching the interview with @EleanorKonik on @nickmilo 's YouTube channel, I figured I’d share how to use Dataview to single out an element a YAML property with multiple elements for those who came here for that reason. Assuming you have made a YAML property with multiple elements, you can use the Dataview command “where contains(property, element)” to isolate one of the elements. For example:
List from ""
WHERE contains(moc, "China")
