Question about particles and foliage

Hi, so to be brief and right to the point, I’m working on a large world and I’d like to use the foliage painter for my trees of course, however I want to have leaves falling from the trees. I’ve already setup the particle system, but I’m a little stumped on how to go about this because from my understanding you can’t have blueprints in the foliage painter, so that leaves just manually placing every tree with a BP setup with the static mesh and the particle, right? Or is there a method to insert a particle system directly into a static mesh that I’m not seeing? Just not sure the best practices for doing this, and would still like to keep it as stable as possible (few draw calls) because again it is a large world. Thanks.
