Add delay for SKEmitter or SKReference for Scene

I'm trying to semi-define some animation with a set of plots. I want to reach SKEmitter

for a scene after some delay. SKEmitter

has a limited amount of spawning emitter, so it's only 1 second, but I want this animation after 2 seconds of another animation. I can achieve this with code, but I would soften the Scene editor a bit if it's not a mature tool (my opinion). Any idea?
