Particle system LOD direct set / forced - How?

Is there a way to tell a particle system / emitter which LOD it should be using?

I can find the option to switch between automatic and direct in Cascade but in other blueprints I can’t figure out how to actually SET which LOD I want in that particle system. Is it by any chance already an existing parameter?

After seeing the LODMethod/DirectSet’s tooltip I’d guess that it can be set from C++ but not (yet) using Blueprints.
As a BP workaround you can use particle parameters to control spawn rate in emitters.
