JAZZ Build snapshots/baselines and stream configuration

I currently work on a project where all applications on the project are contained in 1 stream.  This stream contains multiple components of which at least one component exists for each application.  Currently I use the JAZZ build feature in combination with Ant scripts to perform a build for a single application on the project.  The problem is that the snapshot performed by the build creates a baseline of every component in the stream that the build workspace is associated with and not just the component(s) associated with the application.  My question is whether it would be better to create a stream for each application that contains only the component(s) for the application and possible a common stream for components that are shared by other applications?  This way the snapshots would be create baselines on only the components used by a single application and not all components in the project stream of which are not used by the application. 

Any feedback is appreciated.  Thanks!
