Well, I’m not sure why it won’t let you just set force off of the for each node output. However, if you do manage to do it in blueprint, I do know that “simulate” in the play editor can be used to activate blueprints with cinematics, so at least there is that. 
Also, when creating a movie out of it, I believe the engine will automatically simulate for you, so you don’t even have to have simulate on in that case.
