Automating OS image deployment and application deployment

Automating OS image deployment and application deployment

Hi,
 
If I have a clean OS image without any un-necessary applications. Can I create an automated task where both solutions OS Deployment and Desktop Central Software Deployment work together? OS Deploymet pushes the Windows 7 image after that Software Deployment starts to push selected application packages automatically. Or do I have to make these in separate steps, step 1 OS deployment,  step 2 application A deployment, step 3 application B deployment, step 4 application C deployment ...
 
Kind Regards,
Petteri
