How to rotate multiple actors with keyboard key pressed?

Hi, I have started learning UE for some time now and have created my first level, I have somekind of ventilation shaft in the scene and my question is how can I make blueprint for flaps of that ventilation shaft to open and close with “E” key pressed. I have attached an image for better understanding of a problem.

I’ve made a actor for this and solved in it in the following way

(I’ve added explanation in the Comment boxes)

Thanks so much! I’ll try this out as soon as I can, but I think that is the answer I was looking for!!!
