How seperatly attach beam target and source

So basicly here is question. I need to create beam emmiter and attach beam target point and beam source point to diferent scene components, so target point is follow character mesh (with some relative location) and source is follow some static mesh component (which rotate around character mesh). Function Set Beam Target/Source Point set point instantly in world space, so they not follow character. I can use Event Tick to set target every frame, but what if will spawn emmiter from UObject, it hasn’t Event Tick… So… Any ideas?
