Round Robin if available not working with batch


I have a model with 2 queues on which I can have 12 totes of different products (delivered on batch from a washing process)

The next process is another batch process of 4 totes. Before this process I place a queue to create my batch of 4. Not possible to mix the tote into this process.


The pull strategy "Longest Waiting" is working fine, making a FIFO between my 2 queues.


But I want to be able to test another method "Round Robin if available" but this is not working as I want, the operator will not respect the batch of 4 totes from the same queue but will go the other queue if material is there...

Note: I tried Open/Close ports but the operator is not considering it.


How can I do Round Robin if available for a full batch of 4?

Can the program of the round robin function be modified to round robin each 4 times ?

Here a small model, I want operator to take from the queue a full batch of 4 boxes in alternance OR if not available to take from previous the queue

So, doing a "Round Robin if available" each 4 trays.
