I don't know if someone already suggest this. But in my opinion , It might be good cause When Team Tournament come and player can't online. They can put it in the bank to let teammate use it. Or like Farming Pokemon ex. Theif Quagsire , Catcher Smeargle , etc. It would be like : Having a list of Pokemon in it , Date that someone borrow it , Name who borrow it and more.
Just my sugguest tho :D
