And you can change some parameters of selected objects all at once.
Caution: If you wanna use property "AnimOffset", you have to apply Skin modifier or
other deformation modifier to an object, whose animation is just drived by linked hierarchy.
How to use: Just put this script to \3ds max root\ui\macroscripts\. Then, start up 3ds max,
