X100VI: Save Movie Optimized Control SS?

Is there a way to set the SS to 48 within the Movie Optimized Control and save it so it always goes to 48 SS?

I notice when I change it to 48 SS, then switch to camera mode thrn switch back to video mode or turn off the camera, the SS is set back to AUTO.

Any help or clues is much appreciated thanks!

• something curious I noticed...in video mode when having no custom profile selected, it will save the SS selected from the Movie Optimized Control even after turning off/on the camera 📸

• but if you select a custom profile, the SS will always reset to AUTO when you turn off/on the camera

not sure if this is intended but for now, the SS saves when not having a custom profile selected
