Perhaps I am still not understanding your goal. Can you do the union to maintain the boundaries of the 3 features, and add an identifying attribute like “Feature set 1” for the territory, and add another attribute “Type” and identify water or land. Then set symbology based on the “unique values, many fields” of these attributes? I am assuming you will have multiple territories, but this would allow you to differentiate between land and water, and between territories.
If I am still not helping you, perhaps you should re-post with your full explanation, as a question with this many responses is typically assumed answered.
Best of Luck, Manuel.
