I am trying to produce a map in ArcGIS 10.1 that symbolizes by feature class but also assigns a unique number (as part of the symbol) to each location that will relate to a table embedded in the map that has more detailed descriptions for each location (i.e. location name, address, etc.). My current map (below) has unique symbols for monitoring wells, endangered species, churches, schools, daycares, etc., but it doesn't leave any place for a unique value per location (starting at 1, then 2, 3, etc.).
Would it be possible to create a custom symbol with a unique color (e.g. blue in-filled circle for hotels) for each feature class and then have it automatically assign a consecutive, unique number in the center for each location? An easy out would be to keep the symbology I have and just have number labels for each location. I was just hoping to avoid having to place labels at each location. If the solution requires heavy scripting, then I may not have the skills to do it. Thanks.
Example symbol I would like:
Example table key I would like embedded in the map somewhere:
