How to have total privacy over workout

Hi

On workout privacy setting, I think at the best I can find now is set the workout to be visible by myself. But, on the dashboard, there is a Weekly Leader board summary, if all my workout are set to be visible by myself, it would still popup with a 'lock' icon (for Run, Swim, Bike & Steps as far as I know), indicate I have done a workout privately, to be honest, I dont like that. If a workout are private, it should be totally private, rather than letting someone know I have private workout hidden.

Is there such option exist?
