How to include a default value in Dynamic cascading prompt from 2nd Level.

Question

Hi,
  I use Command Object in 'Datbase Expert' to create 'Custom Tables'  and use these tables to fetch LoVs. I use Dynamic Cascading Prompts in the reports.  I have a peculiar requirement using DCP.
  There are Four Levels as in the Example:
  Continent
   Country
   State
   City
  In the Custom Table, requirement is to create an additinal row with '' that represents 'All Values selected' for that level starting from second.  and The default selection should be '' . I defined that '*' means 'All Vales Selected in the report' This si not a problem. But the problem how to show a default value in a Dynamic Cascading Prompt i.e. how we can make sure in an default value can be selected in DCP from Second Level?
how can the examples 1,2,3 can be achieved detaisled below beacsuse we need to show a default value in Casacading Propmt
Eg of Schedules with DCP:
Schedule 1   
  Continent: Europe
   Country: *
   State: *
    City:  *
  Schedule2:
   Continent: Europe
   Country: England
    State: *
     City: *
Schedule 3:
    Continent: Europe
   Country: England
    State: Greater London
     City: *
Schedule 4:
Continent: Europe
   Country: England
    State: Greater London
     City: City of london

You won't be able to have a true "default" value in the various cascading levels, since there aren't default values in a dynamic cascading parameter.  That being said, I've created a sample report in Crystal Reports 2008 that has a Command-driven DCP with '*' values for the 2nd and 3rd levels of my 3-tier DCP and have accounted for them in the record selection criteria.  You can find the sample here at https://www.box.net/shared/mav5qp337j
