Yeah, I was wondering if I should have used an NSPredicate or not. I'm not a fan of mashing everything together into one line as it makes readability and comprehension an issue, but this is exactly what I was looking for. It's been at least a few years since I used predicates, that's for sure. Thanks. Thank you, Sandor.
