SSIS Missing Package Configurations using Visual Studio 2010 Shell

I'm not sure what am I missing.

I'm creating a new SSIS package using Visual Studio 2010 Shell that was installed together with SQL Server Management Studio. I cannot find Package Configurations to launch the wizard.

Things I have tried:

1) Right Click on Control Flow design. On SQL Server BIDS 2008, I can do that andPackage Configurations ... option is there.

2) From the menu, SSIS. Package Configurations ... option is not there either.

Is it my Visual Studio 2010 installation? Or am I doing something wrong?

Edit: I have also tried http://msdn.microsoft.com/en-us/library/kwybya3w(v=vs.100).aspx - To open the Configuration Manager dialog box. The only thing I see underBuild is the Build <prjname>.
