Group queue pulling task

When pulling tasks from group queue, if there are multiple tasks in that group queue on one case, all the tasks on that case should pull and assing to the user the was pulling tasks. For example, if there are two tasks to order two separate APS's on one case and both are assigned to the 1035 queue, when a user clicks on the queue to get the next task in line, if the next task is one those, both should actually pull and assign to the user.
