Need to have the ability to drag and move contract items in different order

It would be nice just to add items and then be able to move around the contract items so that can stay in order and customize the contract as needed in Group related items together For instance if I put 10 items on the customer items and I forgot about one that I really would want at the top of the list but when I add it it has to go on the bottom of the list It doesn't read well with the contract items it doesn't flow correctly.
