Set Application Pool for Package using MSDEPLOY

Question

I am deploying a website using MSDEPLOY so using something like the below code.

"%ProgramFiles%\IIS\Microsoft Web Deploy\msdeploy.exe" -verb:sync  -source:package=WebAppServer.zip   -dest:Auto -setParamFile="was_params.xml" -verbose >     webappserversync.log

Is there anyway to set the application pool ? I want to do this from the command line and not set it in a manifest or anything like that.

Shouldn't matter but this is in IIS7.
