I have a layer file which I use as reference for symbology for future layers. It is based on unique values, however there is over 100 unique values, and each one have their own icon.
If I apply this symbology to a small layer, its legend or symbology table will have over 100 items, even if the layer only uses 3-4 symbols.
Is there a way to remove all icons that are not been used in that layer?
ArcGIS Pro has a button called Add Unlisted value, and I'm looking for the exact opposite: remove all unlisted values.
