I have an Item that has been added to many different Sales and/or Marketing Streams, and I need to make a change to that Item. Do I need to do this separately for every Stream?
No! Items that you've added to Sales or Marketing Streams are always "reflections" of the original Item that was created in its source Stream (for example, a Blog Stream, or a Flipbooks Stream). This means that if you make any changes to the Item in its source Stream, those changes will also be reflected in any Sales or Marketing Stream which that Item appears in. This also applies if you delete the Item in its Source Stream, which will simultaneously delete it from any Sales or Marketing Streams, as well.
