Fuji X-T3 X-T4 Auto Iso values for video

Hello, on the X-H1 auto iso in movie mode works in the 200-12800 range, with no possibility to change these values and seems to ignore the auto-iso values for stills I set up. What's happen on newer X-T3 X-T4 cameras? I cannot find this information.

The problem is that sometimes I can preview the scene, so I set aperture and shutter speed with a fixed value, but I need a bit of flexibility so.. for example: I want to set Auto-ISO range from 800 to 3200 because I know the scene/room require just this range for the final exposure while moving around the camera and don't want to change values manually for a quick and ready final clip.. but I can't on X-H1. Camera maybe decide to push up to ISO 12800 and footage is bad, and it's not enough to compensate the EXP with the button, I want to limit before it happens, so I have to decide the range for the Auto-ISO (which is smooth now with latest updates into video mode). I want control over it, many other brands allow it, for example Panasonic with separate Auto-ISO value for stills and movie. So, it's not a strange request at all.

What's about the new X-T4 with a separate movie menu? Is it possibile to setup the Auto-ISO range in movie now? It's very basic and useful sometimes, for a video hybrid camera a "must". Doing an upgrade from x-h1 to x-t4 while having same missing features totally not worth it, at least a simple and common feature like this.
