[menupath-raw] does not use right path

I want to use paths for pages and sub-pages that are like:

/about
/about/history

etc, so [menupath-raw] looks ideal. Unfortunately, it assumes the auto-alias of the parent instead of using the actual alias (for example, if I create a page "History" under "About Us" where "About Us" has manual alias "about" I get "about-us/history" instead of the expected "about/history")

Is there any way around this? Should I be using a different tag?
