SALES ORDER/INVOICING

Is there a way that I can sort the items I invoice by category? We have been really busy here lately, and I'm trying to take some time off of the amount of time it takes for me to process an order. I manually input each order and I sort them by bottles and packets manually, meaning, I do all the bottles first and then the packets. Is there a way for me to sort the items after I input them all? Like a magic button that says sort and they just magically sort to be displayed as all bottles and then packets?
