How to make two ASRS vehicles run at the same time, and visually smooth?

I created a new object in flexsim, which is to combine two ASRS Vehicles together, in order to simulate the operation of dual asrs,

I have two situations set up:

1) Ideal situation: dual asrs move and work at the same time

2) Special case: If their respective target items are too far apart, the ASRS on the left will be the main pickup, followed by the ASRS on the right

Now the model looks like this, and it is very close to the effect I want. Some steps are cumbersome. This model is divided into two parts, one is the ASRS process on the right, and the other is On one side is the process of ASRS on the left. Next, no matter which side of the ASRS it is, the ASRS on the right is moving in the horizontal direction, but when loading/unloading, it needs to be divided into who will do it. In this case, when moving horizontally, it is necessary to consider the difference between left and right, BAY, and the different positions of SLOTs affecting the number of SLOTs. These details will actually affect the horizontal movement of the ASRS on the right.

In addition, this model has some visual problems, and it needs to be adjusted by modifying the way of modifying the initial value in PROCESS FLOW.

Then this is my process flow,
