isAggregateMode property
If true, this mode is an aggregation of other, more specific modes rather than being a mode in itself. This includes modes that group Features/Events rather than Gameplay, such as Trials of The Nine: Trials of the Nine being an Event that is interesting to see aggregate data for, but when you play the activities within Trials of the Nine they are more specific activity modes such as Clash.
