I have trail line data in a web map in map view in AGOL. I am symbolizing it by unique values to display different phases of the trail completion. After symbolizing in my legend I am able to see the trail phase. I would like to also add another field attribute to the legend which is owner. The problem I am having is that once I click add another attribute only certain fields show up and owner isn't one of them. Owner doesn't need to have it's own visualization in the map, I just want it to be view able in the legend. If I could figure out how to add visualization to both that would be helpful. Thank you.
