Creating shared, custom border with unique colors for each polygon using ArcMap

Question

In ArcGIS Desktop 10.7 I am attempting to make a custom border for each polygon where there is a:

• shared, custom border
• unique border color
• transparent fill

Here is what I tried: In Properties under the Symbology tab I selected Categories: Unique Values. The default settings shows <all other values> and I edited the symbol to create the custom border. Then I 'Add All Values' and the features populate with the custom border. However, the selected Color Ramp does not apply to the border but instead to the fill. Each border is black with a unique fill.

Credit to @ycartwhelen for realizing this is an ArcGIS Pro feature. Here is the documentation how-to (Set the color scheme target):
