I found one watchface on gplay and designer told me: you can set steps goal target in shealth app.
His watchface was made in WFS
Here is link https://play.google.com/store/apps/details?id=com.watchfacestudio.jeweler_xturbine
My question is: HOW is it possible???
Yeah you can set it but that progress bar on watch face will still be binded to some fixed steps goal (7500, 10000 or else).
Yes, true. I have tested 
The last I heard the Samsung Health team was going to make more items public. But this is a longer experience than other non health related apps.
