How to change path scenario in Virtual Vehicle Composer?

Hello, I am developing some control logic in Virtual Vehicle Composer (VVC). There are some example scenarios like the one below. However, when I use the "Double lane change" scenario, the steering response is a bit weird (too sudden compared to other simulations such as CarSim). So, I want to know how to change the scenario or manually replace the driver model.

I tried once, but it was difficult to consider the related signals from other vehicles. If anyone has attempted this or if I could get some help regarding this, I would appreciate it.
