if you havent admin access to queue item you cannot modify this behaviour.
The only thing you can do to limit the list to your own queue is to create a view through advanced find with the following filter:
Queue where Owner is equal to current user
Then save it and use it as your default view.
This way you can have only your item shown in queue list.
Hope it helps!
