Message for dual steering vehicle

I'm wondering if a common message type exists to control dual steering vehicles (both front and rear ackermann steering). I'm looking for something like Twist or Ackermann_msg.

If not, should we create a new package to hold it or is there an existing package we should add it to ?

There is already the four_wheel_steering msg that can be used

I'm not aware of such a message.

geometry_msgs/Twist has enough degrees of freedom to represent the motion of the centroid of a dual-steering vehicle, but it lacks the acceleration terms that are present in the ackermann messages.

If you want to create a new message that includes the steering rates and acceleration terms, it seems like the ackermann_msgs package would be the appropriate place for it.
