You can download all the subfolders individually. You'd have to go through and get the links for every single one of them. It's a chore either way, unfortunately. But yes, you can absolutely script it if you're so inclined. I'm just not sure it's saving much time/effort that way, at least for the individual. For the community it would save a lot of people time. But then there's the issue of getting the less proficient involved with wget and the command-line. Not sure I'm up to the task of that, it can be hard enough to get people to turn it off and back on again.
