I have problem solving this Niagara problem

So I want those rotating rings to be facing same way at end of their life. But I can’t build the logic. I’m new to the Real-time VFX. Please guide me.

Hi. It isn’t very clear what you want exactly. Posting a video/gif would help understand how they currently face; then a photo with markers showing what direction you want them to face would help clarify what exactly you want.
