Add Snapshot Date/Time to Presentation Items Using Manual Updates

As a Product Manager, I need to be sure that presentation items using manual snapshot update methods have their snapshot date/time present so that:

The update is understood in the correct time context

I have a visual reminder to update content when viewing

I can quickly and easily make side by side comparisons of changes from one snapshot to another without having to manually add text boxes of snapshot timing

so that I can efficiently utilize the snapshot function.
