ArcMap Legend - Get descriptions automatically via combobox "Description Field"

Idea created by mathias.boedecker on Oct 5, 2012
    ArcMap should provide the possibilty to get descriptions for legend items from an attribute table automatically. This should be realize by using a separate "description field" combo-box (see figure) in the symbology dialog. With the combobox a user can choose one attribute field for item descriptions. There is a 1:1 relationship between value field and description field in an attribute table. Therefore every legend item gets its own description for map legend visualisation. The description field combo box should be optional.

    It should be a simple function which reduce copy/paste errors. Furthermore it helps to restore descriptions very fast after using the "Unique values", "Unique Values, many fields" or "Match to symbols in a style" function within a correction loop.
