Ability to create "AND" reports instead of just "WITH" reports using Data Spaces.
In SF you can related objects to each other using "AND" or "WITH". Data Spaces is great with relating objects "WITH" records but I would also like to see the ability to relate objects using "AND". Example is seeing an account with or without a product tied to it in the same report. Data space will show me all accounts with a product but I am unable to produce a report that shows account with or without a product.
