Bundled products (or product pack)

Hello, I am using some installation of Simple Invoices but not the newers.
Is it possible now to create a bundle product (one product that is a set of product, like a box that contain a pencil, a block note and a pen, 3 products in one)? In order that when one product is sold the inventory will decrease each single product of one unit.
In the old SI that was not possible, at least as far as I know.
Thank you, Bye,
Massimo
