Is it possible to use a group filter where you may be able to choose a display field that differs from the field that is actually doing the filtering?
Example: Say I wanted to have a group filter applied to State Polygons, County Polygons, and City Points.
States has a field with Full Name and Abbreviation
Counties has only Abbreviation
City has only Abbreviation
I would like to use State as the main layer and have a list of unique Full State names, but apply the group filter to the abbreviation field, since that is the field that is common in all feature layers.
Is that possible?
