Combining Products / Variables


I have two questions about variations.

1. Can I combine variations?

Eg: My item has 8 bow tie variations, 4 for adults and four for kids. I want to couple them into four options where each option has one adult bow tie and one kid bow tie. So, when the user selects option one, he is, in fact, selecting two variations.

Right now if someone wants to buy, they have to select each item individually and add to cart twice.

2. My item doesn't ship in a box. The supplier has the box for sale as another individual product. Is there a way I can combine these two products automatically?

I don't want to give the user the option to buy the box separately, I want it included as a whole package.
