Must be able to add Dry Ice for multi box orders

We ship a lot of orders with dry ice via 2 Day Air that needs to have dry ice amount listed 5 KG per box or whatever it is. When we ship large customer orders with more than one box on the order ShipStation does not allow the dry ice amount to be selected for multi-box orders. PLEASE get this updated ASAP so when entering each new box to the shipment it can have the option to mark the box has having dry ice or not along with a field for how much KG or ounces or whatever is in the box. I got 20 boxes rejected by UPS today since we had all dry ice details marked correctly but not on the ShipStation printed label do to it not allowing me to include those details on the multi-box labels.
