Todd McDermid is excited about data flow groups in Integration Services:
Data Flow Groups
Data Flow Groups is what they’re calling it, and it’s deceptively simple to use. One of the reasons I’m sure I (and SSIS people I talk to who DID NOT LET ME KNOW IT WAS THERE) missed it is because I was expecting it to be a component in the toolbox. Not so.Code up your Data Flow as you normally would. Then go and select the components that you want to group together – via clicking and dragging a selection window, or click-selecting components. Any component combinations you want. Then right-click and select Group.
I admit that I didn’t know it existed either. This does seem rather useful.
