A suggestion to add here: Physics Handle | Unreal Engine Documentation
Add a ‘get all grabbing handles’.
Right now, if I am holding an object and moving it into an overlap section that will grab the object, the second section must release previous handles. The only way to do that is to restrict the grabbed object to specific actor, and define the value of what is grabbing the object. Then I can release it. This could be made easier and less restrictive to the specific actor class if you were able to get all the constraining handles much like how you can get all the components of a handle.
