Z-Axis & maintaining size

There is a feature in Toon Boom Animate where you can “Maintain Size” while moving an object back and forth on the Z-axis. Does anyone know if there is a way to do it in Toon Boom Studio?
Here is what I’m trying to do: http://screencast.com/t/a2XaxJo7zaco

It is nice feature but does not exist in Toon Boom Studio unfortunately. You have to manually move back and adjust the size according to Camera.
