Feature request: Index S2 option to not show weight

My wife and I share a scale, when capturing our information we would like to be able to not show the weight value but the option is greyed out.

The actual weight is something we would like to track from trending purposes but, other than BMI, is the number we are least interested in, except for trending purposes.

I would like a feature added that allows the weight number to be turned off and only show the user it chose to sync with.
