Handles.FreeMoveHandle + multiple points selection

Hi

Is it possible to make multiselection of points in editor window?
I have a shape from 10 vertices, and I would like to select 5 and move them.
I have found nice example of editable star but I can't swith from single to multipoint edit mode.

Any hints how it could be done?

 void OnSceneGUI () {
         Star star = (Star)target;
         Transform starTransform = star.transform;
         Undo.SetSnapshotTarget(star, "Move Star Point");
         
         float angle = -360f / (star.frequency * star.points.Length);
         for(int i = 0; i < star.points.Length; i++){
             Quaternion rotation = Quaternion.Euler(0f, 0f, angle * i);
             Vector3
                 oldPoint = starTransform.TransformPoint(rotation * star.points[i].offset),
                 newPoint = Handles.FreeMoveHandle(oldPoint, Quaternion.identity, 0.04f, pointSnap, Handles.DotCap);
             if(oldPoint != newPoint){
                 star.points[i].offset = Quaternion.Inverse(rotation) * starTransform.InverseTransformPoint(newPoint);
                 star.UpdateStar();
             }
         }
     }
