I manage a large database of geologic information that includes over 50 different rock lithologies, broken into subcategories using >10 headings in the contents page-> symbology. These groupings are necessary for the legend in the layout and also in the map to examine and interpret data. I have put together a style with polygon symbols for each lithology type, but if I change the style (e.g., update the color) and re-apply, I lose those headings and once again have a long list of unique values, sorted by name or some other meaningless index. It would be great to have a way to have the heading information, and (bonus) the desired order of values stored in the style so that when I re-apply the style to the polygon layer the headings come up automatically. I've looked into the style dictionary- awesome concept- but it seems to be more about dialing in symbols based on attributes rather than organizing the list of symbols in the table of contents. Thanks!
