A linked container that works like most others, except that you can connect it to circuit networks and filter specific slots.

This even bypasses the normal restrictions that space exploration places on ALL linked containers. You however cannot depend on this for any automation where the ID is set to anything other than what Space exploration sets initially to the chest. You can still manually change it, but as soon as a space ship launches/anchors, the ID will be RESET to the ID it was originally given.

Be forewarned that this breaks the balance of Space exploration, which is why this is marked with the Cheats tag.
