FEATURE REQUEST - Keep exposure when switching custom modes

[IanH]

I frequently find myself wanting to switch between film color presets if I think a different one would be better for the scene — the issue is when I switch modes I need to update my exposure settings again since I’m primarily shooting in Manual exposure. It would be nice to have a menu option to retain the exposure related settings (ISO, Shutter, Aperture) if I’m switching from one custom mode to another so I don’t have to waste time changing my ISO and Shutter and possibly missing a shot.
