Publish service that is symbolized on multiple attributes

Idea created by Tiffany_CALFIRE on Oct 13, 2016

    I would like to be able to publish a service where the symbology is based on at least two attributes (Unique values, many fields).  We utilize published data in the Collector app, so being able to show more than one attribute would give the user more information on the data that is already collected, and allow us to keep the information in separate fields (right now we have it concatenated into one field) so that we can run queries and reports on the collected data more easily.
