Add 'muscle %' in wellness Data

Hello,
Would it be possible to add ‘muscle %’ in the wellness data (my body-weight scales show this)?

thank you

Is it not better to just stick with body fat%?

Tbh: I’m not sure :-/

Though it does seem that losing (measuring) fat achieves one goal; gaining (measuring) muscle achieves another.

In that - I can lose weight ie body fat by not eating (and thereby lose muscle), but gain muscle by working out and eating ‘correctly’, and also lose body fat.
