Allow Titles to be part of a Page Template

This is a feature request to allow page titles to be part of a page template. This would allow template creators to enforce a standard page title in a format required. For example, they might want to enforce a title of

CR-XXX XXXXXXXX

Where X is a sample value, so a sample page would be

"CR-123 My CR Title"

This would help by standardising page titles, and allowing users to follow a convention. When it comes to using things like the checklist macro - it would make things much easier there.
