Order

I'm fine with the chronological order of photos in the general feed, but I have a few tagged portfolios that I would like to display in a fixed order. I know date/time labeling them in the filename will do this, but then that date/time is displayed on screen. Is there a way to order them whilst hiding the date and maintaining a caption, which will also be in the filename? I tried using nested dated folders, which I guess works although they need to be numbered in reverse to display in the correct order.
