Blender 2.8: Restrict influence of Force Field to its Collection How do I restrict the influence of a Force Field to the Collection it's in?

I'm trying to simulate falling leaves in Blender 2.8.
I have a Collection with the Leafs_Emitter particle system and a Vortex Force Field inside it.
I want the Force Field to only affect or influence the falling leaves inside the Collection.
But currently, it affects all the other particle systems inside my scene.
I hope it's not too late for this answer, I just found out how to do it. In the properties of your particle system, at the Field Weights tab, there's an option named Effector Collection, select the collection where your force fields are and that's it.
