Add support for adding a prefix to a title to avoid title conflicts

[jeffmercerVG]

I have a doc structure where every folder has a page in it with the same title. For example:

FolderA/Overview.md
FolderB/Overview.md

The upload to Confluence doesn't like this because it would try to create two pages called "Overview". I have a code change I can contribute where a folder can opt into using the parent page's title as a prefix. In Confluence, it would end up uploading two pages:

FolderA - Overview
FolderB - Overview

If this concept is acceptable, where should I PR into? the develop branch?
