Recreatinig intermediate and thumbnails

[chadeldridge]

Is there a way to recreate the intermediate and thumbnail pictures for only a specific group of pictures.  I have about 7000 files in this one specific gallery and the recreate function from admin tools starts at the bottom of the list and not the top.  I dont really want to click my way through the files 45 at a time.  Is there a way to tell that process to either start at the most recent uploads or to just do a specific directory of uploaded files.

Thanks in advance.
