Reactive Physics With Anchor Points?

Hello! I generally figure out most of my problems with a google search or trial and error. However, I can’t seem to figure this one out. I have a bridge spline that I want to dip when I walk on it. Is it possible for me to be able to set anchor points as posts? I want it to act similarly to the cable component in that it has anchor points. (Please note I’m a noobie when it comes to in-engine physics, ha ha!) Thanks, in advance!
