I'd like to add, for example, a weather forecast widget on the dashboard.  The widget has pre-defined cities to select from.  I'd like to create a custom profile field of those pre-defined cities.  So when the member chooses their city, that field gets passed onto the custom text/html box and onto the widget script. 

Something like {custom_profile_1} that can be replaced into the widget code where "Los Angeles" would be.

Any suggestions greatly appreciated.
