Zdzdy Adult Insulated Lunch Box for Men Women Reusable Lunch Bag Large Capacity Lunch Tote Waterproof Cooler Bag with Adjust Shoulder Strap For Office Work Picnic(Grey)

Great product. If maker is reading, have one request. I put random stuff in top part, and bottom gets lighter after lunch causing it to turn upside down when I carry. Is it possible to put small straps on left or right side to 'keep' the carry shoulder stap attached to the top of the lunch box so it does not turn upside down when bottom part is lighter than top?
