There is no truly good way to determine the information you need. If in your environment you do not use the Dequeue step, you can use the Calls Dequeued metric on reports. When you see this statistic (from scripts that do not utilize the Dequeue Step) you are seeing a caller being answered by a queue and dequeued from other queues they are in.
In a scenario where there is only one roll over queue you can count on this information. If there are multiple, it becomes a bit fuzzier.
The only way I know of is to add additional logic to your scripts and appropriate markers so you may run a custom report against it.
