as you might have noticed, there are hundreds of features that users want, and we work toward accomplishing them.
the ability to manually edit other data fields is something that we want to accomplish. we are not picking on you or excluding you because you do not own a tanita scale. the scale does not have internal memory or a display for the user to see what the scale just recorded from them. that is the supplement that garmin connect satiates for the scale owners: a display for the users to see what data has been recorded from the scale.
please respect that your needs have been recognized, and stay tuned to forums to find out if/when your desired feature will be added.
