Solution to set and have a control of a different Camera Target for each individual view

I am experiencing an issue with the target setup of the camera.

I need to render in Batch mode and set a different depth of field for each camera view in the scene. The Vray camera setup options are as follows:

• Fixed Distance

• Camera Target

• Fixed Point

What I would like to do is define the camera target for each view. However, I have been unable to find any information or settings to determine where the Camera Target is located. It has often occurred that the camera target has been calculated incorrectly.

At the moment, the only workaround I have found is to manually adjust each individual scene one at a time during the rendering process. However, I would like to launch all renders in Batch mode while maintaining control over the various settings.
