When you're looking at total giving over the course of a year - you want to omit transactions that are not an actual donation. It would be fantastic if, when creating an event form you could modify the gift type to classify as "event ticket", then modify any additional donation that comes in on top of it as a "one time gift" this way, when you are pulling out reporting, you can more easily filter out transactions at the gift type level, rather than having to go all the way down to appeal.
