I tried to load all my chest , because it's a huge mess , and sadly the mod only the shulker , how i can mix it everything with the usual content of the chest , i'm gonna have a ton of chest and shulker , so i look to see if i can have like : X amount of Stone if i include all the shulkers everywhere , and like 200 not empty shulker box , to kinda prevent the problem of how many differents items i'm gonna have

Added in 2.5.0; shulkers (and other stuff like bundles) will unpack contained items.
