Maybe someone here can help me with this. I need to either invert the order of my symbology labels (note: NOT feature labels) or find a way to only have the upper value of each class display as the label. I have reached out to the extent of my network and nobody can think of a way to do this. AI can be useful when finding existing documentation from the ESRI website, but neither we nor it can seem to find anything about this anywhere.
I need to either swap the order of the label ranges (large to small/left to right) or only display the upper value as a label. I have to make dozens of maps with this same general scheme so I would love some kind of automation or setting to do this by default rather than making a manual edit each and every time.
I have a line of code that should be able to make the swap easily, but I can't find any sort of "Format Labels" or "Label Expression" dialog specifically for these symbol labels. I looked at a few expression dialogs but they only seemed to filter the data fields themselves, not the symbol layers.

I swear I have done this before and done so easily, but my memory wires may be getting crossed. Any help you can offer would be appreciated!
