Niagara - easy way to fade out a PS with BP?

Just wondering if anyone knows an easy way to fade out a particle system via blueprint rather than just toggling it off? I was thinking of using a color param and fading out the alpha, but I’m working with multiple systems that switch depending on the surface type, and I don’t think a global alpha value will work. I was hoping there was a way to parameterize the visibility and fade it out, but that’s probably not a thing is it?
BTW the particle is a looping effect.
