How to move a grapple point on a platform at the same time?

Hi! I’m currently working with a Grappling system. It works fine with static grapple points, but I’m want some platforms with grapple points to move at the same time and in the same direction, as if the grapple point was really on the platform. Anyone has an easy way to parent those two objects? The platform’s animations works fine, my character detects and grapples to the point without problems and I’ve already set all the Objects to World Dynamic.
