How can I increase the default traffic density in the City Sample (UE5.6) for Sequencer?

I’m trying to change the traffic and crowd density in the City Sample on Unreal Engine 5.6 while working inside a Level Sequencer.
I know that during Play mode I can press O to open the traffic settings and increase the density there, but this only affects gameplay.

What I need is to change the default density values so that my Sequencer animations don’t load with the standard 50% density.
Instead of the default 0.5, I want it to start at 1.0 (100%) every time.

Does anyone know where the base density values are defined, or how to override the default settings so Sequencer uses higher traffic and population density?
