I'm building a simple report but I need to attach a Retrieve Spec that will select records based on either of two elements having data. 

Is there some way to connect the Search Menu command to the report?

Or, is there some way to invoke one of the Retrieve Specs via programming?  I'm able to invoke the "Meet Any Requirements" command via programming but I don't know how to invoke a specific retrieve spec via programming.

Any help would be appreciated!
