how to add translation to existing G8 rigging?

The shoulders only have rotation dials, but no translation. Is there an easy way to enable that somehow? I tried bone editor but see no obvious way. I just want to move the shoulder joint a bit on the X-axis, to get a more realistic result in my pose.

You would use the Joint Editor to adjust the origin, if that's what you want.
To make the shoulder "shrug" up, you need to select the Collar joint and move that.
