Hi @Eddiegoqo, in exploring some options, I found it difficult to make the ASRS vehicles all move exactly the same way. Even an On Draw trigger matching the positions won't do the trick because as the model speed increases the visuals will lag. You could possibly create your own custom task executer and create animations for the load and unload activities.
I'm including an example where I only use one ASRS. I added 2 more slides and extenders to the vehicle and made sure to put them in as subnodes to the original slide so the animations would stay (see this post). This makes it so the ASRS will have 3 levels that will all move together.

I then changed the logic of the model using process flow so the three items will be loaded at the same time instead of one at a time. In order to get the positions right, I followed the third answer on this post in making a fixed resource in the ASRS that the 2nd and 3rd items get moved into so I can adjust the positions. The example model goes until the items are moving back onto the conveyor at which point they will move one by one again. I would suggest moving the logic on the racks into process flow and use custom logic to get the ASRS to do what you'd like. I would disconnect the a-connections so none of the ASRS 3d logic is trying to be used. That will give you more control over moving all the boxes at once.
Let me know if you have any questions!
