adding "arc" to a layer transform move

Is it possible to set a keyframe or add an “arc” to an animated layer transform.
For example, if you set a begin frame for a ball then an end frame how do you add a simple arc in the middle. Are all the moves linear?

Hi,

In the current version of the software the layer transformation do not have paths so the way to make an arc of some sort in your layers would be to split your shots in multiple panel and make the move from panel to panel.
