manually take boxes round robin fashion

I would like to have the audit operators manually take random boxes off of the conveyor line similar to what is currently happening on my model. In my model I have used queues because I cannot achieve my desired actions. Can anybody help me? Here is my model on jumpshare my file; https://jmp.sh/tKpMDbA

FlexSim 18.2.3
distribution of boxes to audit stations in a warehouse

If you run my model you will understand what I mean.

The boxes come in on my Zero Pressure Accumulation conveyor and operators are meant to manually take boxes off in order to audit them and do a quality control process.

@Juan S4 Please read the manual. In there is a part that is called "Creating Conveyor Logic" and it explains how to randomly divert products to a side conveyor. You can use 2 decision points for every combination of main conveyor and audit conveyor. But you can also use 1 decision point at the beginning and there already define to which auditor you send it or if you let it go on.

Hi Steven, thanks for your reply. I am aware of this logic. The reason that I did not use this logic is because; my challenges are; 1) getting the boxes ( a maximum of 2 per auditor at any one time ) spread evenly to the auditors ( audit time can vary randomly from 60 seconds to 180 seconds ) - hence why the round robin [if available] queue strategy works so well. The second challenge is doing this sortation manually by letting the audit operators manually fetch and take the boxes off the conveyor as it passes them.

Initially I used the random divert via decision points but then one audit station can block up the main in feed line if it is already filled with 2 boxes and the third one is waiting to enter it and hence blocking the boxes behind it from flowing past it to the other audit stations ( this is never how it would work in reality as the auditors would only grab a ( random ) box from the main line when they are finished processing ( auditing ) their current box.
