Basically, add a [s $2-radiobutton-update] in the [originator] after the [OSCroute /preset]. And then add a [r $0-radiobutton-update] in the [pd save] or connect that straight to the radiobuttons. What do you think?

Actually. Just add a [s $2-substate-r] will do the same thing as the above, no change necessary to the parent patch.
