We use a snapshot to roll out and manage websites in other sub accounts. Most of the content is generic, but on some pages, there is content that is bespoke to that sub account. When we want to push out updates, such as changes to text copy, design or images, it overrides the whole website, which means we lose the bespoke content. We really need to be able to select only specific pages to update (or better still, sections of pages) and not the whole website when we push out an update. (We even lose the favicon link!).
