Advanced Search Filters allowing matching across different variables.

I often come across situations where I want to match one variable or classification with another in a subrelation report.

For example,

1. Billing City = Departure City (to understand how often people buy tickets for flights departing from their own city)
2. Gender = Product:Gender (to understand if the customer specified gender is same as what the product was targeted to)
3. Campaign: Target category = Product: Product category (Did visitor buy the same product category for which the campaign was targeted)

(Note - I am using ' : ' to denote classifications here)
