I have some electric utility featureclasses that have some fairly complex symbolization requirements.
I would like to leverage Dictionary renderer to symbolize them.
However when I go into Symbology and choose Dictionary all I see are military choices.
How do I create a new entry for this dropdown called Electric?
I looked here, but didn't see anything to indicate this can be used for anything except military purposes.
I tried copying the mil2525d folder to Electric, and renaming the contained .stylx file to Electric.stylx.
However, that had no effect on the dropdown list in the Symbology UI.
