Sorting of Items in Gantt View

Hello, I am setting up a gantt view for a dashboard. I want to preserve the sort order of items as they are ordered on the board. It appears that the gantt view is re-ordering items based upon the date field that is chosen for the gantt view. How can I preserve the sort order of items as shown on the board? (I feel like I must be blind and missing the configuration option somewhere!)

Thanks, Scott
