This read-write OCTET STRING encodes the full desired permutation, or ordering, of all units in the stack in one write. An admin reordering an entire stack at once can use this single object instead of setting each unit's desired position individually, simplifying bulk reordering operations. For example, to fully reverse a 4-unit stack's order in one operation, the admin writes an octet string encoding the reversed sequence to this object rather than updating four separate position values.
