Is there an option in Power geopak SS4 using Create Point Control, where I can reference a null point of a reference corridor, right now the only option is to reference Linear 3D Element of a reference corridor?

Is there an option in Power geopak SS4 using Create Point Control, where I can reference a null point of a reference corridor? Right now the only option is to reference Linear 3D Element of a reference corridor? My Template has a backbone which is comprised of null points which controls lane locations and slopes. Depending on the location, the linear Elements can change from roadway to bridge, whereas the null points stay the same. I am looking for an efficient solution.

Thank You
