It would be useful to be able to base a query on a previously defined query instead of just a BO or BO Group.
For example if I defined a query based on the Person BO that listed "All Persons" then I could then create another query "All Living Persons" to ensure that I did not inadvertently pick up someone in the database that had passed away. Subsequent queries could then be built on the All Living Persons secure in the knowledge that I didnt inadvertently send Christmas cards to dead people or their loved ones.
Should some condition change that had a large number of dependent queries then just that one level would need to be changed in order to modify the output of a whole set or queries and reports.
Thoughts and comments?
