Vmware App Volumes VERSION: 4.0.1.35

We have updated our app volume server to version 4.0.1.35.  And when we create a package for an application the only option is to use a 20 gb size vmdk. As you know smaller apps like notepad++ does not need that much space.  How do we create smaller vmdk templates for version 4 like what we had with 2.X app volumes? is there a KB artical on how to do this for app vol version 4?

Thanks
