multiple-level menu

I have an app where I need a multiple level menu.

Think of this problem:

  • I have 5 bags (orange, blue, pink, red and green) in car 1
  • I want to copy more than one to car 2 and 3.

What do you think of this kind of menu?

First, the user selects the bags after that is possible to copy to multiple cars…

EDIT: My bags are tabs, where I manage products. I want a way of copying without needing new enviroment, a new click... I tried this, but I want something more immediate.
