P: Auto-Stacking Order Options

Stacking; Currently, Lightrooms Auto-Stacking by Capture Time stacks the files in chronological order.  I create stacks based on multiple edits and it would be nice to have an option to select the stacked file order.  example:  stack by newest to oldest, stack by file name.  I typically would prefer to see my most recent edited file on top of the stack.  This would allow me to view the most recently edited/best file when in the "collapse all stack" view.  Now I have to manually move the stacked file to make that happen and if/when I accidentally unstack an entire folder it is extremely time-consuming to go back and restack thousands of files in the preferred stack order.
