Hi everyone,
I'm working on a map in ArcGIS Pro and I'd like to remove the borders around each symbol within many classes of many feature classes(hug data set), essentially setting the border width to 0 pixels. Ideally, I'd like to avoid opening each symbol individually to make the change.
Are there any built-in tools or techniques in ArcGIS Pro to achieve this efficiently? Any suggestions or workarounds would be greatly appreciated!

Thank you,
Hala
