Rigify - restart/reset to initial/default state I have a generate rig by rigify

I can apply some animation and change custom properties, for example neck follow in the chest &quot;bone&quot;

I can delete the animation and restart the transforms with  Pose / Clear Pose Transform / All menu (or Alt+G, Alt+R, Alt+S to clear location, rotation and scale)

but I can't restart o reset to initial state the custom properties, for example neck follow in the chest &quot;bone&quot; don't change to inicial value.

How can I restore the initial configuration of all bones and controllers, values, visibility and other properties?
At this point, I don't think you can restore the initial state for these values. There no defaults for these.
If you're starting anew you could set a keyframe for all values at frame 0 or something. Then if you delete all keyframes at frame 0 you'll have the defaults.
