X100V: Unable to change Camera Settings in multi-exposure mode

[Mathieu]

I am looking at reproducing the multi exposure solution here to achieve a bleach bypass look: https://fujixweekly.com/2020/02/24/my-fujifilm-bleach-bypass-film-simulation-recipe/

Sadly, after the 1st exposure, the X100V does not allow me to change the camera settings "set" through the Q memu, to select a whole set of settings. Instead, I can only change some specific values, which is not really practical.

Someone would know how to do that ro an alternative ?

Thanks!
