I've been storing herbs in some SDB's, and when I harvest them and go to put them in, I have to remove everything that is in that SDB to add the new herbs. For example, if I have 20 Hairball Flowers in an SDB, and I want to add another 10, I have to take out the 20 to add the 10 and make the stack 30. Is it possible for me to just add the new flowers, or do you always have to remove to add? Thanks for the help :)
