Another reason I want separate measure shelves is that I want the bar-in-bar gantt to represent two measures (project duration and committed duration), and then the other measures to be shapes represented on top of the gantt bars as markers.
Not sure i understood this part of your query, but does the attached help for having a shape per milestone?

Hi Srinidhi, thank you! Very helpful. Another approach that I learned recently is to pivot my milestone data in order to get the bar-in-bar data and the milestones working together.
