I know what you mean! It has not been an issue for me because the flashes lie flat on the umbrella and octobox brackets, thus disabling the camera's settings. So the on-flash settings stay as set.
If you set 0n-flash zooms and do not touch the camera's Zoom menu, and take a shot, do the set values stay as set?
