Mulitiple report types

I would like to see a way to run a few different report types. We're holding an event with classes and I'd like to run a seperate report for the class registries and also a guest registies report rather than have to manipulate the one report in ecxel after downloading. Or maybe just a way to build a report for example I want all only specific fields to show as columns in my report.
