The video below is an overview of how to "bulk tag" a group voters, so the data point can be used in lieu of re-running the same queries with multiple criteria again and again. This allows you to use a default criteria of your choosing with a single dropdown from any query screen.
This type of bulk tagging also allows you to merge different tags into a single tag.
You can access the bulk tagging feature at Voter Data > Query Data, where you will run the query before choosing the option to have the voters from your query bulk tagged. As shown in the video, you will need a System Tag created before bulk tagging begins.
