I don't know whether I would call this a bug or a feature request, but it just feels clunky to have to drag them in every time.

You can shift click out, but not in. https://github.com/WayofTime/BloodMagic/blob/master/1.7.10/main/java/WayofTime/alchemicalWizardry/common/tileEntity/container/ContainerTeleposer.java#L82-L86
There is code to handle shift clicking in, but it does nothing... I don't know if this is intended to be disabled or if it is just an over sight.
