Help setting beam points in niagara

Hello, anyone have an idea if it’s possible to make in niagara - without using blueprints/c++ (just everything inside niagara system)?
I want to spawn a beam from niagara system position, the end position would be a single particle that dies in a radius from that niagara system (its inside the same system). I tried using death event and location event combined but I’m not sure how to use that data to set beam end and start position. When I was trying to set beam start or end inside module, it wont compile (Cannot set external constant error) and I have no idea how to resolve that problem, any help would be appreciated!
