I see, if all items have the same phase offset, you can move them all at the same time, no problem. In any case, to answer your question, yes you can access sample data and move items via scripting and achieve what you are looking for.
Also, there are many scripts in the Reateam reascripts repository. Installing the Reapack manager extension too. http://reapack.com/
How did I begin? I don't remember, but when you start scripting, it's a trap, you cannot exit anymore. Be careful
