I thought since this dialog involves explicit user interaction this  
is okay and not restricted by Rainbow?

I'd simply add a query parameter to the ChooseObject() DBus call.  
Since no shipping activity uses this call directly AFAIK, it should

The Python ObjectChooser's __init__() could grow a "query" keyword  
argument so it would be compatible with existing code.
