Display last date published date/timestamp or lock published pages so no more edits


I have a development team working from a prototype and they need reassurance that everyone is looking at the same version.

Is it possible to lock pages within a published axure file so that no more edits can be made? So there is one truth.

Or if not is there a way to display on the prototype the date/timestamp showing the date/time that the page was last published?

Any help with managing this would be much appreciated.
