Feature Request: Open Container

If I have an open container (backpack, case, plate carrier, etc..)in my inventory it would be neat for the quick move hotkey to move the selected items into that container rather than just the open locker space. Not a necessity but I feel like it would be a solid minor improvement to the inventory system. I've tried to get this to work in the past. Please correct me if its already in and I just missed it lol.
