You need a custom statistics collector for this, but it's fairly straightforward. I think you can still listen to the OnEntry of the exit conveyor. The trick is to specify something like
data.item.subnodes.toArray()
as the Row Value. When the Row Value field gets an array, it updates all the rows associated with that field. In this case, you're telling the stats collector to update the row for all items inside the pallet, rather than for the pallet (which likely doesn't have a row in the first place).
Let me know if that makes sense, or if you need more guidance.

Accepted solution
Going off of what Jordan said, I modified the Warehouse Demo to do something close to what you wanted. First I added some labels to the Process Flow so when a flowitem is created it adds the "timeCreated" to the item (0 for the initial inventory, other times for the Inbound items).
Next, when the pallet was being loaded to the conveyor, I set a second label to each flowitem for the stayTime which is just the current model time minus the timeCreated label from earlier.
I made a Statistics Collector to keep track of the Staytime of each item as the pallet enters the conveyor. From there I made a Calculated Table to calculate the average of the Staytimes partitioned by the SKU. Then I made a graph to display the stats.
