I frequently do historical climatology studies with optimal routing and I think it'd be awesome to be able to export those files and save them. I found an Optimal2.dat file which seems fairly large and must contain some sort of data, but loading it into a fresh copy of Expedition it doesn't seem to load the routes. Currently I think the way to do this is to export each as a .gpx? This works in theory, but when you have dozens or hundreds of routes I don't think there is currently a way to do them in bulk and it becomes tedious.

I think it'd be awesome to be able to export specific sets of optimal routes as a file and load them back in at a later date.

I'd say this is obviously very low priority, but it'd be a great feature.
