I received this message from one of our customers. Is there any way to make delivery requests save with the saved order?

"This is just a comment/suggestion for a saved order. I chose to save my order last week and reordered that this week. One thing I noticed is that my delivery instructions did not save. I work at a college and I tried to give detailed instructions for the driver to help them find me. It would be nice if the instructions saved with the order so I don't have to type them in each time."
