sort feature for rearrange items module

It'd be nice if the rearrange items module had a sort feature that would sort the items like you can in the Edit Albums->Sort Order. Like a one time sort.

This would be nice for a large album where the majority of items are sorted in a certain fashion, but you still wanted to be able to manually change the order of a select few. Right now if you do a sort order in the edit album and then change back to manual sorting you lose the ordered sort.
