May be it will be better to introduce a unique identifier for each queue.
On default the identifier is not specified and it will trigger all objects and instances with that behavior (as it was in the first version).
Set Parameter - make an option: "make queue unique" and it will use UID of the object/instance as an identifier.
Action:next/pop can use object's uid for that speciafic object or use default value for all queues
