At present, I can't see a way of aligning individual or a group of ApplicationMenu2010 items to the bottom of the ApplicationMenu2010.  In Microsoft Office (2019 and probably earlier) applications, there's a group of less-frequently used application menu items that are displayed at the bottom of the application menu.  I want to replicate this layout in an application using the xamRibbon. 

At the moment, I'm looking at faking this using a top margin on a separator that is bound to a viewmodel that calculates the appropriate margin; seems like a lot of hard work that should be easier to achieve.

I thought that VerticalAlignment of the ApplicationMenu2010Item would do it, but this doesn't seem to have any impact.
