I don't order a lot from the Q anymore for a variety of reasons but have returned multiple items in the same package in the past. If there are two return slips (e.g., not in the same order), I tape the return slip to the corresponding item. If they are on the same order/return slip, I write in big letters how many items are being returned. I've also successfully challenged customer service on multiple shipping charges for items returned together. Shipping is a profit center for the Q and they want to maximize it.
