How to put items to depot from all of my backpacks.

Before i start, sorry for my english

I want to deposit my items from backpack, but i have hmm lets say "backpack in backpack" and in Cavebot i got option Open next backpack, so i created script which is going to hunt, then go to sell my loot, and after thati would like to put rest of my stuff inside depot. Im collecting health potions, creature products etc. So after selling items elfbot closing my backpack and reopen it, so when my character goes to depot he put inside only items from first backpack, is it even possible to make him open next backpack even if its not full just to put other items from next backpack ? I hope you guys understand what i mean its little bit crazy. I tried to make full backpack of backpack and opened all of them and unchecked option from cavebot to open next bp, but when he goes selling items the trade window opens and it close some of them and i got just few open and its not enough. Its chaotic but i beg you guys, help me If you dont understand something just let me know i will try to explain, as i said my english is not good so it can be chaotic
