Hot to limit the number of collision events triggered for the whole niagara emitter?

Hi!
Is there any way to limit the number of collision events triggered for the whole emitter?

I have a niagara emitter that spawns a bunch of particles, and they spawn a decal when they collide with the ground. I need only the first particle that hits the ground to spawn a decal. Is it possible without any tweaks in Blueprints?
