I did but it was very general. They told me there was no need to be super specific.
For example, I had- Box 1: winter clothes, dresses. Box 2: books, notebooks, photo albums. Anything unusual I would mention specifically - like: mask and snorkel, ukulele, mini trampoline.
I made a rough list while I was packing and then typed it up. It didn't take much extra time really. It was also very helpful for unpacking as I had a list of where things generally were.
