You can grab a script from all objects (for example from from a previous project) using this command:
This will go through all the objects in project (Menus, Movies, VM Commands, First Play etc.) and check if it has Custom Commands in the "A" section (before Abstraction layer)
If yes, a new block will be created with the script. If object has no custom commands then no block will be created.
If you need to grab VM Code from only one particular object use Add Block Handle instead.
