I need to modify the quantity of a couple of my products where if you order 1 product there are actually 20 of the items that will come in the order.  Is there a way to display this other than the description field or have it calculate the total number of items ordered?  For example, if water bottles come in quantities of 6, so if you order 3 of them, you will receive 18 total water bottles.

Thanks for the help and love the site.
