[Niagara] Is there a Significance Level setting in Niagara like Cascade has?

Hi, I’m loving all the Scalability settings that Niagara offers, I was wondering however, is there a Significance Level setting like we had in Cascade? In Cascade you could set an emitter to have Low Significance and when the frame-rate dropped that emitter would be disabled allowing for more important emitters to stay active based on their Significance Level setting.
