We have a page where we store all the outdated pages. We want to keep the pages around since they contain historical information. The issue is that users can find these pages using search and not easily notice that they have been moved to the archived page tree. Is there a way to change the parent page in this tree such that it would add some warning text to each child automatically? I thought maybe I could change the Page Template or Page Layout for the page and have that apply to its children, but I was unable to find any way to do that (maybe it's possible and I don't have enough permissions to do that).
Ideas?
